Ah, you're right!  I just figured out what happened.

1. Enable electric-pair-local-mode
2. Type, without leading whitespace (naturally):

   int foo (int a,
            /* hello */
            int b)

Upon reaching '(', electric-pair will insert ')', and as you keep
typing, it will be carried to the new line.  So, when the comment is
opened or closed, the indent engine sees that and figures "ah! there's
more text on this line, I'm a leading comment" and reindents
accordingly.

So, my initial description was indeed incorrect.  Sorry about that.

Shouldn't have doubted you!  That's nice :-)
