Greedy atoms anchor again. Until you acquire a lot of practice, it's probably impossible to keep all these rules in mind at the same time.

Mickael Ruau's insight:
Lookarounds often cause confusion to the regex apprentice. I believe this confusion promptly disappears if one simple point is firmly grasped.

In fact, that's a useful technique.
