I took the pint as saying that Apache/MIT/BSD/MPL code that is distributed as part of a GPL project is actually under GPL. To obtain the original Apache/MIT/BSD/MPL code you need to get it from upstream. So that if project A originally licensed as MIT is statically linked inside a project B licensed under the GPL then in the event that all copies of project A source code are destroied except those distributed via project B (a more likely scenario before mirror servers) then project A is now only available under GPL. I believe that GP relies on the fact that GPL source code can only be statically linked with other GPL code and so "compatibile with GPL" means "can be relicensed under GPL" rather than "can be included as is in GPL works"
