Right, because string->symbol does not match the "string*-symbol" glob.

But here "minibuffer--bitset" does match the "minibuffer*-bitset" glob.
I.e. the "-" you typed matches the second "-", not the first.

I.e. for string->symbol, you'd need to type "str>sym", at which point it
would correctly expand.

That would make sense, yes, but it would require more changes.  You may
want to start by looking at completion-pcm--string->pattern.
