This small change seemed to fix the invocation of a PI, but it shouldn't have been needed.

Detailed but not too intense, I guess.
I don't have the 'context' to understand this fix... ;-)
Without a PHP background, explaining the flaw is difficult; it requires context that is not straightforward to simplify. The bug was under the hood in MediaWiki, where an oversight was made inserting new code elsewhere. In the interest of transparency, the "exact" answer to your question is provided in the link. The more general answer of "Deep PHP hoodoo" usually works concisely enough when we explain such fixes, but I didn't want to leave you thirsting for more information if it was in your wheelhouse.
