They're just all right. A mach equals to sound speed, 320 meters per second. So when she performs this skill, she is at Mach 1.

And, breaking the sound barrier too fast (say, for example going repentinely from 200 mps to Mach 1) under a dense atmosphere, like Earth's or Equestria's, the object breaking the sound barrier won't resist such pressure and would desintegrate. That's because only in cience fiction movies that ocurr in the space the characters travel to light speed repentinely, like in Star Wars.

And, by supossing that breaking the sound barrier is that easy for Rainbow Dash, it isn't just too much effort resisting the breakage of the barrier and then going faster? I mean, a F16 jet plane can do it, but that's because they're made of steel… what if a living being brokes the Sound Barrier? Would hurt just too much to whistand… and survive.
