When I went in for the next round I had a look at the then parked up tandem, an Orbit, and noticed it had both disc and V brakes on the rear wheel.
Are you sure it was a disc? Many tandemists use a drum brake on the rear wheel to give controlled braking on long descents - this is known as a drag brake (we have one on our Megabike). It allows you to mitigate the tandem's tendency to go downhill like a homesick brick without cooking the brakes and wearing out the rim.
Drag brakes are often worked from an indexed gear lever on the pilot bars.

Yes, discs front and back with a v-brake on the back. I studied it in detail but forgot to look at the levers, the second pint of kamikaze had kicked in.

In which case the V-brake is almost certainly a drag brake.
