If an AVR did that, it would seem that the sound field would be in disarray.
Space is crucial when using wides as one member here mentioned, so I'm currently utilizing a 5.0 in my particular set up.
Prior to this, I was using a 7.2 using wides, my room was 15.5w x 26D. my seating was 13' from a 64" display. When a car would drive off to the side either L or R of the screen, the sound would follow, which would really widen my front stage.
In a bar scene, the camera is focused on the bar, off to the side, out of sight, a pool game is going on. The wide speaker produces the sound of that game, not seen but heard as if it were actually taking place in the next room (the movie Invincible for reference).
According to the quoted statement here, if I were using rears, and the car drove off to the side, the sound would carry off but only behind me. IMO, that effect would not be realistic. If I were using heights, the sound would then go up, again, not realistic.
My AVR has never processed sound this way.
I've experimented using all three different channels, heights were great for thunder, jets and planes flying overhead, but the content was limited.
My rears got even less content which was surprising to me. When I employed wides, the AVR utilized much more content. Using bookshelves were fine, but when I used a pair of towers as wides, a whole new level of sound opened up.
To address one concern mentioned earlier here, having five speakers across the front does not over power the rear, on the contrary, in my set up, it was perfect. My FXiA6 di/bipole speakers offer so much sound, having wides was a great balance. The di/pole speakers put sound in front and in back of you as well as the side. I would put my wides up against any rear set up any day of the week.
One other thing to mention about AVR's sending out the same sound to different channels, my AVR utilizes Audessey DSX, this separates intended sounds for different channels
