I have to say that trying to understand the relevant parts of perlre can feel like doing a structural analysis of the propositions of Wittgenstein, but I'll give it a try:-

I would say that the behaviour has to be explained by a combination of three provisions of this documentation:

1) "/g"match globally

2) "?="(update: "lookahead and ..." ) match best (see #3 below) and chain global matches

3) "match best""the earliest match is always the best."

More update: oops that's four provisions, er, amongst our provisions are, er, "I'll come in again"
