It does accept at least two.
My wife and kids are dual nationals, so have both passport stored and we can select the right one for our trip. O am not surprised that it does not accept two of the same country... As only one can be valid at any time.
I have a China.visa stored, which is like a second passport, that comes up automatically... so, kudos to UA it.
