It was based on the incorrect assumption that python and php choose between alternatives the same way POSIX does. As per my recent emails to the mailing list, that assumption is false; they try the alternatives in order. This makes POSIX EREs and perl/python/php REs fundamentally different when alternatives are used within a repetition, and nobody should expect to see the same behaviour for patterns such as "([ab]{6}|a)*?b".
