It's only an Issue with Hydraulic Disc Brakes , if there is a right and left lever
and you have to drain and refill the lines ..

Moto setup gets used on my Touring rig useful in the Steep get-off-and-push hills.
, Cyclocrossers have favored this too, so you can brake just before a barrier ,
to slow down, braking the rear wheel ..
even after the right leg is on the left side of the bike, right hand is on the top tube.
