One might ask, "If, at the bottom of the ramp, the disk is going faster than the ring is, why do they both get to the bottom of the ramp at the same time?" The simple answer is that they don't. The question posed was:

How does the forward velocity that the ring has, when it gets to the bottom of the ramp, compare with the forward velocity that the disk has, when it gets to the bottom of the ramp?

This question neither implies nor states that the objects were released simultaneously side by side. If they were, the disk would make it to the bottom first. You are not asked to compare the forward velocities at one and the same instant in time, but rather, at one and the same elevation, namely, at the bottom of the ramp.
