This is true for all absorption. For example, putting absorbers on the
ceiling over a drum set makes the ceiling appear to be much higher. If you
think about it, there's no difference between a ceiling that's fully
absorbent and one that's infinitely high. Either way, sound that goes up
does not come back down later as a reflection.

Ethan, how do you feel about diffusors above a drum kit or above a listening
position, as opposed to absorption?
