He said that binary derivative works containing MS-PL code could be
under any license.  I'm concerned about derivative works distributed as
source code.

The only thing he said about this is "The purpose of requiring
that source code redistributions be made only under the terms of the
Ms-PL is to allow developers a choice of a license that will ensure that
their source code will only be distributed under terms that they have
explicitly chosen. [...] The Ms-PL provides developers a licensing
option that ensures their code will be distributed initially and later
under terms and conditions they have chosen and agree with."
