This is not a new clause, it has been the standard latex conditions for some years. Unlike GPL software which forces derivatives to be under exactly GPL, The LPPL is rather more flexible, you can distribute derivatives under any licence you like, so long as this main clause is maintained. If you want to issue a derivative under a different licence, you could for instance just say explicitly ... this software distributed under the conditions of xxxx ... and in addition subject to the constraint that no derivatives of this software are given the filenames of the original source files for this code which were released under LPPL these: are x y z.
