The unit can regroup if someone assaults it, but few are foolish enough to try and kill an already dead unit.
Not necessarily foolish; you might have shot the unit that turn with the intention of charging it, so if the unit falls back (and you are lucky enough to still be within assault range), you can still attempt to assault in order to avoid being shot at. It's especially useful if you're able to pull off a multi-assault. Or you could try to charge a unit that's falling back in order to gain extra distance (to take an objective, for example).
But, barring a few situations where it'd be tactically useful, it's pretty pointless to charge a unit that's falling back.
