In (info "(elisp) Active Keymaps"):

   When the key sequence starts with a mouse event (optionally preceded
by a symbolic prefix), the active keymaps are determined based on the
position in that event.

I don't know what the "symbolic prefix" means here (maybe it means
something like `down-mouse-1'), but I think it doesn't mean the
`gnus-symbolic-argument' in Gnus.  It is confusing here.

The phrase "symbolic prefix" is only in:

  (elisp) Active Keymaps
  (elisp) Searching Keymaps
  (gnus) Symbolic Prefixes

It isn't explained in the first and second node.  And the third node is unrelated to the first two nodes.

Good question.  Maybe this is referring to the case where the mouse
event is on a side element, in which case the key sequence starts with
`header-line', `mode-line', `left-fringe', ...

I think the least confusing thing is simply to remove the clause in the
brackets. It doesn't add anything useful. A mouse event is a mouse
event.

Sounds fine to me,
