Anyways, $ make x& make y& wait cannot always be rewritten with -j. $ make -j[whatever number] x y will act differently except for special cases of x and y; probably when both x and y have no dependencies.
make x& make y& waitwill only work correctly if x and y have no dependencies in common. Otherwise, the two separate make's will get in each other's way when they work on whatever is in common. This fact has nothing to do with parallel make or "make -j".
Anyways, with -j examples added to the manual, we would get on the right track about how to use -j.
Since your two examples have nothing to do with each other, I don't see how you can reach this conclusion.
