The only thing that might be a reason for the rear caliper placement, is
the routing of the emergency brake cable. This is just speculation, but
if I was designing where to put the rear caliper, I would place it where
the least chance of binding the emergency cable or brake hose was.

Subject: Re: [Spits] Non Triumph, rear disc brake question -
For a moment I wondered about the vertical forces - a caliper at the
3-o-clock position will be pushed up when braking, and one and the
9-o-clock position will be pushed down. But then there will be an equal
and opposite force on the brake disc, transferred to the axle, and since
both the axle and the caliper are supported by the hub the two forces
will cancel out there and not make it into the rest of the vehicle.
So, no, I can't think of any good reason why the rear calipers should be
in the opposite position to the fronts.
