Not a bug, unless I misunderstand. From :help /\@<= you can see:
The part of the pattern after "\@<=" and "\@<!" are checked for a
match first, thus things like "\1" don't work to reference \(\)
inside
the preceding atom. It does work the other way around:
Example matches ~
\1\@<=,\([a-z]\+\) ",abc" in "abc,abc"
It's documented, which makes it a "quirk" instead :-P
