It makes sense really if you think about it, the paper part of your licence is ONE piece of paper:
If your get points driving the car - it goes on that piece of paper
If your get points riding the bike - it goes on that piece of paper
If your get points while its a provisional - it goes on that piece of paper

All points on all catagories accumulate on one licence, if your banned from the bike your banned from the car and vice versus. It doesnt matter if other catagories are on that licence once its taken away they're all taken away. To get the catagroies back you have to re-take everything as if its from day one. Although I dont think you'd need to take the CBT again as thats a course its not part of your licence.

EDIT: further note, once you pass everything and get it back, you've got another 2 years of careful riding to go.
