My guess (and it's only a guess) is that you can change Drums from one RealDrums type to another RealDrums type, but they are all RealDrums.
Conversely, you can change a Guitar RealTrack to a Piano RealTrack. They are all RealTracks, but different instrument types.

I agree it's possibly a little inconsistent, and I guess that's part of the 'evolution' of the product. Also, the instrument 'name' in the mixer never changes, leading to more confusion.
