That sounds completely wrong, actually.

The contents of /var/tmp are expected to survive a system crash, as that
is where vi, emacs, libreoffice et al are expected to store their
recovery logs.

Not much point putting the logs somewhere where they will be deleted by
the very occurrence they are intended to protect against ...

And yes, the rules for /tmp are "don't expect to find anything you put
there will be there a few minutes later ..." :-)

Cheers,
Wol
