No, that's definitely not what he did.

If you read the GPL, you will find that the whole "any later version" thing is not actually part of the license. It's being used in the example of how to apply the GPL to your work, but the license itself does not contain any clause like that. (In fact, if it did, the whole "GPL v2 or later" vs. "GPL v2 only" distinction would be meaningless; the GPL v2 would already say that any later version is also acceptable, and declaring a program to be licensed under "the GPL v2 only" would make no sense, just like saying "licensed under the GPL, but you may not make copies or modify it" doesn't make sense, either.)

It's important to keep this in mind. Linus licensed Linux under the GPL, but he never used the "any later version" language, so Linux[1] was *always* licensed under the GPL v2 only. The change you mention merely made this explicit to combat confusion.

1. That is, the parts he holds the copyright to, as well as Linux as a whole; individual parts contributed by others may well be available under additional licenses, such as later versions of the GPL, of course.
