Well, first off, the GPL does not include an explicit reference to
That said, the GPL requires that copyright notices be kept intact. So,
if the person who offered both licenses didn't provide a clear statement
about this exception to the GPL (that the MPL copyright notices may be
removed), it might not be legal for people to remove the MPL copyright
That said, if the copyright holder intends for people to remove the MPL
option then he isn't likely to care, and the issue is not likely to wind
up in court.
It might even be that only if you have someone like SCO involved that
the case would wind up in court.

Even if we consider this phrase to refer to license version, there's
still the issue that it's an explicit part of the license terms, and
the GPL has special requirements about license terms, beyond those of
a normal copyright.
Alternatively, if you're talking about the use of this phrase in a
copyright notice: Yes, in that context I agree with you.
