No, it doesn't :).  Your example does result in an error because of
the empty braces after left num (guess, it's a named parameter in the
real example).

But that's irrelevant to the actual problem (once you g/c the leftover
braces).

Actually, to the contrary, it ventures into rather obscure corners.
@DropCapTwo is a galley.  When you hide it inside a definition like
that, the galley is never considered, iirc.  You need to look up the
details of galley promotion in the expert's guide.  It's been more
than a decade since the last time I actually remembered anything about
that.

Hopefully, Jeff can provide a real answer.
