Sorry, but you are wrong.

> I also don't think "this is a license for anyone not the copyright holder" is accurate. The license specifically prohibits removal of the license you can't "dual license" GPL code.

The terms in the GPL applies only to the licensee. Unsurprisingly the copyright holder still holds the copyright and is not bound to the term of the license.

> Can you rescind a GPL license?

Nobody is rescinding the license here. Whoever got the source code under the GPL license will keep having the rights to _that_ source code. What you call rescind, is in fact licensing the existing code _also_ under different terms, _and_ new modifications only under the new terms.
