Looks like the code has been like that from the beginning: ccd58722df
"Add lisp/gnus/registry.el.", Ted Zlatanov, Tue Apr 5 23:37:02 2011
introduces the file (it has been moved once since then), and the code is
already the same there.

I can only guess that the intention could have been to distinguish (mark) from
(mark SOMETHING): prune the first because the mark field is empty.
Anyway, seems it never worked like that.
