At a given RPM I believe it does mean that you are going the same speed.

I agree that if the top RPM isn't reached before the belt reaches the top of the pulley you will keep accelerating until top RPM is reached.

Agreed, but the speed will be the same at a given RPM because the gear ratio is the same.
With all that being said I'm sure there's a curve. Meaning, if the engine can't reach top RPM because of a lack of power it wont reach top speed, I also suspect the belt wouldn't go through it's full range of motion, in this particular under powered scenario.. I would think this would more likely happen with heavier rollers not lighter though. If the rollers were too heavy it would essentially try to shift to the higher ratio too fast for an under powered engine
