We've offered sound acoustic reasons why above is better than below, but there are of course reasons other than acoustics which may dictate or at least influence choices.
Well, you may not have thought the sound would be degraded in this setup, but it will. But that's ok too, because how much and how sensitive people are to that varies, and the end result can still sound fantastic. Which may be well above the "good enough" bar to let other factors become more important in the layout.
I'd be careful about making such an absolute statement (even if followed by YMMV) based on non-blind auditions of different equipment in different rooms on different days (sheesh!), when the differences literally are quite easily measured. Like so many things in audio... you may not actually care about the differences, but they are there.

"The worst place for a center channel is below the screen"
I stick to this as an accurate statement^ and believe it to be true beyond reasonable doubt. I did qualify the statement above, with my saying we are only talking about the center of the front wall (where reasonably a center should be located). So unless you are talking about putting it in the side, back, floor or ceiling, or perhaps another room- then indeed below the screen is the worst place for it.
"Worst place" meaning that the alternative of behind the AT screen, or above a fixed screen is a better place.
Now that we have established my viewpoint (I thought it was pretty clear already) we can discuss why you think that perhaps below the screen is not the worst place for a center speaker? I would welcome any information I don't know, or might not have considered.
Also please keep in mind that just because below the screen might not be the best place, does not mean it could not work well in some situations. Many situations are unique and different, and my comment was based on generalities.
I have zero desire to get drawn into a debate or semantics, but I do I have genuine desire to discuss why or how one location might be better or worse in regards to acoustics and sound quality.
No offense taken at all. And by the same respect I mean no offense when I say that I'll trust the speaker placement choices of one of the inventors of Dolby Surround more than some guys on an internet forum. I know that doesn't read well on a forum post, so like I said no offense or derogatory undertones meant, but the fact that Roger chose to place his center speaker in "the worst place" speaks volumes to the "mountain out of molehills" analogy I made.
Do you really think he would have spent all that time and money on his HT and then decide to place the center speaker in "the worst place" he could possibly place it? I'm sure if someone of his caliber with his experience and education in the audio field would have thought for one second his sound was being severely compromised, he would have gone a different route. Just say'n.

What you say in bold is correct, but one would have to ask why you would have placed your center so low in the first place. If there was no option to place it higher then yeah, you would want to explore other options. The placement of my center speaker is in no way hampered by any obstacles and that goes for BOTH rows of seating whether upright or reclined. Take a look for yourself.
When I designed my theater I ensured the center-line of the center channel would be as close to ear level as possible. Given my screen size (11ft wide 16x9) and ceiling height (10ft) I was able to get the centers center-line no more than 5 inches from ear level. Hardly something I would consider a game changer or a night/day difference.....Sounds/dialog appear focused on the screen.
