Not true. The original author can release the code under two licenses.
Perl for example.

No. The original author can release the new version under any license they
want. Or even the same version under two licenses. Licenses are not
binding on the copyright holder.
Examples: Perl, Alladin GhostScript, anything LGPL'd.
Even without involving the original author, if the second license permits
the GPL to be applied - e.g. an X-style license allows this - you can add
the GPL as an alternative license and continue to provide the code under
