According to the PGN standard:

-----------------
8.2.5: Movetext RAV (Recursive Annotation Variation)
An RAV (Recursive Annotation Variation) is a sequence of movetext containing one
or more moves enclosed in parentheses. An RAV is used to represent an
alternative variation. The alternate move sequence given by an RAV is one that
may be legally played by first unplaying the move that appears immediately prior
to the RAV. Because the RAV is a recursive construct, it may be nested.

*** The specification for import/export representation of RAV elements needs
further development.
-----------------

So both are correct.
