Yes this is it.

This Lojban is too advanced for me.

If you are right here - & I am not competent to judge - then I will
have to rethink everything I've been saying, for I had thought
exactly the contrary. If your example is non-specific, then I
guess it would be negated by (or false if):
   not exists(x): Mark waits for x
while if x is specific, then the negation/falsification is:
   exists(x): not Mark waits for x
And I would normally understand the former to be the normal
negation of the quantifier.

But I am out of my depth here, and should cede the field to those
who eat lambda calculus for breakfast (along with their 3 shredded
wheat [culture-specific reference: a pity there's no .UI to
mark this]).
