If he has told her, then she's probably just noted they're never in the same place at the same time, and that Merlin is invariably absent when Ahbraim shows up, plus they have similar mannerisms in speech and body language that Merlin simply couldn't hide from a person well versed in spying.
When did Aivah meet Ahbraim?
And as to them being in the same place at the same time - remember that we are talking about a conflict spanning an entire world - the fact that two individuals have never been seen in the same room is NOT reason to say they are the same person.
For example, has Ehdwyrd Howsmyn ever been seen in the same location as Sir Rysel Gahrvai? Is that enough evidence to say that they are the same person???
