I'm assuming in the example above that the .pcre file actually contains pcre syntax, not regexp syntax.
It's a typo. But surely you're aware the syntax is virtually the same[1]; pcre just has a few added features not available in standard regexp that make writing some expressions easier.
The main reason pcre is preferred with postfix is because it's faster -- and occasionally magnitudes faster -- than the vendor-supplied regexp library.
