Literally, it's "does not correspond to reality," which I think is a pretty good translation here.

which is, of course, not true
which doesn't jive with the truth
which, of course, I'm not

for example

Sammy's suggestions are freer, but accurate. I would just point out that "jibe" is the most common spelling for the word in the second example (though a lot of people do say "jive").
