Yes, which is why you shouldn't do it that way. make -j2 [target] && make install clean won't try and run the install or clean targets in parallel. [target] should be 'buildworld' or 'buildkernel' for compiling world/kernel. For ports, parallel compilation isn't likely to work for a lot of ports so you shouldn't complain if it fails; but if you want to try it then you can use what Pete suggested.
