I think it's because for a non-negligible portion of the player base, thespianism and invocations of colo(u)r are among the principal purposes of play.Why would I say that, when it makes no difference to my action resolution?
One thing that I enjoyed about combat in 4e D&D is that fiction actually matters to resolution, and that resolution generates lots of colourful fiction.
It's similar to some posts in other concurrent threads about how the only difference between two characters that actually matters is how they're "roleplayed", i.e. how their personalities are invoked during freeform narration.
