Ah, yes, sorry for being unclear: the search for a match goes backward,
but the matching itself goes forward.
The docstring of re-search-backward is more clear about that:
The match found is the one starting last in the buffer
and yet ending before the origin of the search.

It's not the ideal behavior, admittedly. It's even more obvious in
`looking-back'. But fixing it would require the implementation of
a backward regexp matcher.
