If I read the pkg source correctly it uses regex with some glob-like preparation like converting * to .*.https://github.com/freebsd/pkg/blob/62302ab4b4d69528e155ea7b68f058a05d6dffdd/src/updating.c#L71And it indeed checks if the word contains regex characters. If not it compares with strcmp.
strpbrk(words[i],"^$*|?") == NULL

What is remarkable is that it compares to "origin". I think origin is the full portname "lang/python". The regex match also matches a substring of origin.

This would explain why pytho? matches, but python didn't.

NB: this is by  looking at the C code for a minute with my rusty C skills. I might have overlooked something. 😅
