same shipsets for 2 opponents in game

[Emperor's Child]

I've joined a PBW game recently and have noticed that two of the opponents that did not provide a dowloaded ship-set have had the computer select for them the same shipset. I'm not in contact with either one at the moment, but am curious if this will cause issues in turn processing down the road. I need advice from players who have seen this before on what problems to expect and advice on how to tell the two apart when they have ships in the same sector.
