I don't understand this "interspersed empty substrings" way of looking at regexes; I suspect that it doesn't make sense some of the time, and is not useful, but my suspicions may obviously stem from my incomprehension.
A pattern like [ac]* on its own matches everywhere; so vim does the substitution everywhere. Why is that not intuitive? Anyway, as I see it, vim is consistent.
Doing substitutions with a pattern that matches the empty string is not useful, in real editing tasks it's not what is wanted. One is always trying to match *something*.
