The comment is slightly wrong, yes.  For correct results you need to
either:

1. inherit module (not module-base), which does:

addtask make_scripts after do_patch before do_compile

and will ensure that the scripts are built before your module is
compiled without you needing to do anything else.  Or...

2. inherit module-base and arrange to call do_make_scripts() explicitly
from your own recipe.
