Hmm. Here we go again: is this actually documented somewhere?
How about the procmailrc(5) manpage?
There are some special conditions you can use that are not
straight regular expressions. To select them, the condition
must start with:
! Invert the condition.
$ Evaluate the remainder of this condition according to
sh(1) substitution rules inside double quotes, skip
leading whitespace, then reparse it.

Seems like a good enough explanation to me.
