There are a lot of semantics at work here.
For example, you ask about variables being passed. A custom tag is called
while the calling template is being processed, so all of the active
variables in that template are in memory. The caller scope allows the
custom tag to reference those variables, creating, at least in concept, a
pointer.
AFAICT, this is entirely a single threaded operation, so nothing happens in
the calling template until after the custom tag has executed.
