What happens when you return from a subshell:

$ x() { (echo hello; return); echo two; }; x; echo three
hello
two
three
$ x() { (echo hello; return); echo two; return;}; x; echo three
hello
two
three
$ x() { (echo hello; return; echo next); echo two; return;}; x; echo three
hello
two
three
$ (echo one; return;); echo two
one
bash: return: can only `return' from a function or sourced script
two

So in a function, return ends a parenthetical subshell (without error) and
continues on within the function after the parenthetical (and you can return a
second time from the same function because the first didn't count), but return
will NOT end a parenthetical (without error) outside of a function call.
