Um, then what's the point of clause 9 at all? The GPL is invoked only
upon distribution. No distribution, no invocation of the GPL, no problem.
"You" (the licensee) have the option of distributing under the GPL 2 only,
when you invoke the GPL by distributing the Program, whether or not you
have modified it. Clause 9 is not preceded by any language indicating
that it applies only to modifications, so it must be considered valid for
any invocation of the GPL.

Clause 9 does. Clause 9 also pretty much states that all versions of the
GPL will be compatible "in spirit". A non-backwards-compatible GPL
version would invalidate the first paragraph of clause 9, so the second
paragraph will never be checked against.
As an aside, there is precedent for a common licensee relicensing code,
ironically perpetrated by GPL-devotees, most often on BSD licensed code.
In fact, I submit that since the GPL is the most-often-switched-to license
when there's a licensing switch, there is a very real, however very small,
portion of code that was never intended to be GPL'd that is now relicensed
under the GPL, often by people with no more status than that of common
licensee WRT the code in question.
