I believe it actually will check its cache first, even though this
seems illogical.

It will pass it either to the original server, or to a parent server if
a parent is configured. (Which could be bad, because the parent server
might be configured to cache it even if you're not.)

Also, some web servers might not have cgi-bin in the path for cgis;
"cgi" is a more conservative match string.

An improved configuration, IMHO, might be:

acl QUERY urlpath_regex cgi \?
no_cache deny QUERY
always_direct allow QUERY

This is what I use currently.
