No.  Parallel builds with -jN are indeed supported on Windows since
Make 3.81, but not the jobserver.  The impact is that the sub-Make is
always invoked with -j1, unless you explicitly override that in the
sub-Make invocation command line.

You have here only one level of recursion.  To see the difference, you
need more than one.
