Yes.  From https://wiki.asterisk.org/wiki/display/AST/Handling+Special+Extensions:

"When a call is hung up, Asterisk executes the h extension in the current context."

Your log statements illustrate exactly what the description of the h
extension on the wiki says it does.  Your call is not hung up in the
conference context, but in the macro context testmacro.  Hence, it looks
for a hangup handler in that context; when it doesn't find one, it exits.
