Because of the rules of the GPL, there was never a point were PiDiP wasn't available under the GNU GPL. The BSD license with the added clause can not override the original GNU GPL. It can be offered as an alternate license to the GNU GPL as long as the complete sources are available under the terms of the GNU GPL.
It's not provided as an alternate license because nowhere it is stated that the user may pick one of several licenses.
The program has to be clearly licensed under an umbrella license that lists all the alternatives. Not doing so and just providing two licenses is potentially a contradiction, which can be alleviated by assuming that both licenses apply at once, but then clause 4 of GPL forbids additional clauses under penalty of termination of license, therefore, this particular combination of licenses cancels itself and so PiDiP's license is the default "All Rights Reserved" with about a dozen authors involved in several different teams.
