firstly LOL
but yes, alot of the better athletes in the sport practice things both ways, so sometimes it makes sense going the other way, they need to prepare for this as comps can be ridden completely differently like this. if a right footed rider is riding a comp set out by a left footed rider, this kind of thing happened ALOT in the hampshire comp series, was very annoying. but would have been much more annoying if at a world championship for instance.
I tried it many years ago before the days of the half bash! when middleburn ruled the world. I mostly just couldnt get the power for the bigger moves, and for rolling moves it did my head in and i had a few stupid bad crashes. Now a days i only ever have the left foot forward for lining up a 1/2 pedal stroke up/gap, when pedalling and when skipping from one foot to the other on the back wheel, which can be useful for lining up to a wheelie tap, but mostly for fun!
