That too falls into the "I play HH alot more that Dbl Bass, so why not put it in the best place" logic.
I also have the double pedal on the outside, but I don't go with this logic. The way I see it, since they're different pedals which do different things, there is no one best place for both of them.
Having the hi-hat close the the snare gets it in a good place for playing (to avoid crossing over the hands). Whilst the pedal's a bit too close to the snare drum, it don't play anything too tricky on it, so it suits me fine.
The bass pedal on the other hand, is far enough away to stop my leg interfering with the snare drum, and allow me to play insanely fast double bass (just like the guy in the MD ad).
(Actually, my double bass is rubbish, I'm just dreaming...)
