There is perhaps some extra opportunity in a 10-14 day solid observation window, but I don't see why a satellite version couldn't still work in smaller windows.
Another reason could be testing for building a much large radio antenna on the moon's surface in the future which is mentioned to farther down in the article. The moon itself and it's dust has electromagnetic effects that might effect measurements and learning about them now could help future planning.
You'd build an array (see e.g. VLA mentioned in the article or SKA), and it is much easier to combine the data from an array if everything isn't flying around and so there are varying distances between the antennae.
Not for radio telescopes, but how is the current state of optical interference? Would it help if we didn't have to use adaptive optics to compensate for atmospheric turbulence (and have subtly different images at the different telescopes)?
