Yes, this is expected behavior:
http://www.gnu.org/software/make/manual/make.html#g_t_002dw-Option

Basically, using $(MAKE) has special behavior, which is fortunate most
os the time, but fails for this specific case, where the second 'make'
is completely decorelated (Makefile-wise) from the calling 'make'.
