Command line parameter /r

When we say that only one ROOT patch is allowed with the parameter /r, does it apply to each single instance of vvvv (doesn t seem like it is the case) or as a overall? And if it is the first why isn t it allowed a ROOT patch for each instance?

it is of course one root patch per instance of vvvv. the one you get to via ALT+R. makes sense?
