Yes, that'd be one option - and probably the simplest - to do it. One can create several signal paths with that unit, it is possible to create one stereo path which goes to FOH and another one which goes to an FRFR speaker on stage. The reason to do so is to get a more 'amp on stage' kinda feeling through dialing in an extra path with different settings.
Since all those devices (Axe-FX, Neural DSP, Helix and whatnot) recreate a sound which is taken from a specific spot at the virtual speaker via a virtual microphone, it is not uncommon to use some different settings for the stage. The sound which goes to the PA might be perfect for mixing, but not necessarily what one wants to listen to on stage while playing live. Hence the idea with the satellite combo speaker - some guys say that using that kinda cab instead of the cab simulation and an FRFR speaker gives a better playing feel.
