Ah, I believe the problem is triggered because the atoms after the
":%s//\=@o/gce<CR>" are interpreted as answers to the y/n/a/q/l/^E/^Y
prompt. The back-tick is ignored and the "a" (the subsequent atom)
is interpreted as "a"ll the remaining matches.

For this to work (actually prompting the user), the
":%s//\=@o/gce<cr>" has to be the last item in your mapping, leaving
the :s command in the user-prompting state.

I'm not sure I completely follow your process. You have words
flagged with "@@" that you need to ask the user about, potentially
adding them to a reference word list (which it looks like you're
storing in the Z register). Do the "@@" remain at the end of the
process? I see them getting replaced by "qq" but didn't see them
getting returned to "@@" at any point. With a sample "before" and
"after" document, along with what/how you want your reference
word-list and the y/n answers you gave, it should be possible to
rewrite this mapping so that it gives you the functionality that you
want.
