Of course it does, but that has to be used on every update and installation of package that has nodejs as dependency (which lets be honest not a lot of people look into before installing a package).
This pseudo package helps nvm be the only source of nodejs regardless of installs and updates. Since the package is in aur, it doesn't have to be used if you want to do the hassle of using --assume-installed on every install and update. Having a choice is a good thing in my opinion.
