Why are you expecting your fossil partition to become more empty?
It's a cache - so even when a block has been copied to venti, it
is still useful to keep a copy in fossil as well, in case it's referenced
again.  It will be marked 'clean', so that it can be evicted from the
cache instantly if fossil runs out of space.

Are you still worried that blocks aren't being copied to venti at all?
You can check by looking at the archive score which is printed
on fossilcons right after a 'snap -a' is done.  You can use vacfs
to mount this score as a fs, and then explore that to see if everything
is there.

If you *really* want to empty your fossil partition, you can reformat
it immediately after a 'snap -a', using the '-v score' option with the
score of the snap you just made.  (Take the usual precautions first,,
of course.)
