Where does that law say that he can only exercise it if it looks like an irregularity is about to occur?
Law 42 B 2 "He (dummy) may try to prevent any irregularity by declarer".
This suggests there must be a potential irregularity for dummy to prevent.

Playing from the wrong hand is a potential irregularity, and reminding declarer which hand he's in will hopefully prevent it. It doesn't say that he can only prevent an irregularity that's apparently about to happen.
I lock my door to prevent someone from robbing my home. I don't wait until I see a potential burglar.
I personally wouldn't remind partner about this when I don't see him about to make a mistake, but I don't typically play with partners who need this help on a regular basis.
