Suppose a group of Hellions were in CC with Logan Grimnar and the dice gods are kind to the point that they not only survive the initial round, but actually have a chance to yank him away by the beard from his squad.
The DE player knows a couple Hellions don't stand a real chance of winning this combat and opts to sacrifice the couple remaining Hellions by having them leave the table with Ragnar in tow.
Legal or bogus?

You can't leave the board unless permitted to, such as falling back. They even put it in the rulebook FAQ.

As above. While H&R is performed like a fall back move, it isnt actually one and youre not allowed to wander off the table while doing so.
