That is going to give faster rebound, where having the taper up "A" will give faster compression and slower rebound. Most drivers run taper down "V", but a guy at my local track runs it the other way and it handles the rough stuff very well. It scrubs a lot on jumps and landings though with the faster compression.

I think it's more common in Europe to run "A" style since those tracks tend to have smaller jumps.
