It's written confusingly (not the first time for a zsh construct :-/).
It's particularly confusing given that "<<HERE" is indeed a special
construct.

What you're looking at is a normal < followed by a <(list),
i.e. redirect stdin from <(list).  So see PROCESS SUBSTITUTION in the
zshexpn manual page for details of <(list).  So yes, indeed, it does
work pretty much like an input pipe with slightly different implications
for job control.
