Because that makes the script 10x more complicated or 10x slower.
Either you have to store the tempdir path somewhere
(/run/checkupdates.tempdir) or you delete the fakedb and redownload
all the sync repos each call.

The only benefit I can see would be slightly better support on
multiuser systems, but you'll be running into issues there from
pacman's own lockfile.  If multiuser support is an issue, the best way
around that would be

fakedb="${fakedb:-/tmp/.localsync/}${USER}/"

Allowing two people to run checkupdates at the same time.
