The only difference being the frequency of the comb filtering. The only thing to watch is that the same audio doesn't get mixed with something that has gone through the link. Or mixing two mics, one local and one remote that share the same acoustic space.

Though the link probably should not be needed for mixing anyway. It wouldn't take much to create a script that "respawed" the link if it was needed.

Just out of curiosity, what kind o data throughput did that create? 100mb links? Switch and or router in the middle? Just curious to the interaction across the wire. 1024mb/s (GigE hardware is more modern, firmware typically closer to current) vs 100mb links. The common theory would be that gig 'pipes' only become relevant when data reaches capacity near or over 100mb. Bit like the 32bit vs 64bit OS argument in some ways. Perhaps the differences will be negligible in the end game. But it might be the difference of running that 64/2 link at 32/2... Too!
