Sure, you'll get some benefit from them simply being in the room, but it seems like a waste of effort if you aren't maximizing the effectiveness by placing them in the right spot, no?
I assume that you are most recently referring to RJTX's pictures? I would agree that they are too high to maximize their effectiveness in the room, and I am not sure if first reflection point measurements were done either.
In general, I do agree completely with this that if you are going to go through the effort and cost that you should be trying to place them in locations that will yield the best bang for your buck.
I have brought that up in the past here, and since this isn't the more hard-core acoustical treatments thread, I haven't pushed it much.
A lot of people are going to looks and still reducing flutter echo and such in their room, even with "poor placement." For them, the looks are more important.
I spent a lot of time working out first reflection points (marked them off for all 3 of my front main speakers and for all 8 seats) and it was basically close enough to a solid line along each wall. Everything is a compromise until the point in which you treat, for example, the entire wall slightly above tweeter/ear height (which should be close to the same) down to the floor. So while I have my front most panels set up for the closest speaker to that wall and my personal favorite seat to sit in, I am not being as effective for most of the other seats. It is still a major improvement in the room, but even with those areas accounted for, it is still not completely ideal for maximizing acoustical performance for all seats and with all of the main speakers.
So thank you for bring this point up again. It is important to do, but not everyone here is worried about it. They are OK with "good" improvement. With a little planning and placement tweaks, they could get "better" improvement, with "best" being a LOT more treatments and probably the scrapping of the poster panels altogether.
