Yep - all that's happening is your MIDI routing isn't updating when you change the plug in. Just go to the Instrument section of the channel & change your output to the new VI.
Edit to add: It doesn't change on my set up BTW - I've always had to change the Instrument output when switching VI's; I'm interested that some users don't have to do this. Until now I assumed everyone had to change it manually. Gotta love PT!
