I'm one of those GCC people taking care of the library and I can assure you I don't particularly appreciate that style (like some other things in the V3 STYLE). So, I would say that you should be very careful in drawing conclusions from things you might read in the V3 source code -- not every one has the same idea of the styles to be used.
It is not a matter of style: it is a matter of respect for the users.

Naturally you'll also see the opposite:
From stl_algobase.h:
template<typename _InputIter, typename _OutputIter>inline _OutputIter __copy(_InputIter __first, _InputIter __last, _OutputIter __result, input_iterator_tag) template<typename _InputIter, typename _OutputIter> inline _OutputIter __copy(_InputIter __first, _InputIter __last, _OutputIter __result, input_iterator_tag)
and so one.
Huh? Looks like a copy-and-paste error...
