They are processed differently -- IIRC, in general {$$vars} is intended
to be an "immediate substitution".  In other words, one that is
intended to take place "as soon as it's encountered" -- even before
markup processing begins.

That said, figuring out the correct sequencing of markup variables
has always been tricky.
