Experiments as well as some code I found online both seem to imply it is perfectly fine to have multiple AUGraphs providing output to the Remote-I/O Unit, however it wouldn't be the first time, that something seems working and then all of a sudden acts strange or breaks completely and when I file it as a bug, the answer is "This was never allowed in the first place and it was plain coincident that this was ever working for you".

AFAIK the restrictions with kAudioUnitSubType_RemoteIO AU is that you
can have only one per graph, but the number of graphs is not limited.
AUHAL (RemoteIO in iOS case) is the abstraction between hardware and
your audio graphs.
