That was done by a previous owner, for some reason.
Some people will use longer bolts and then put nuts on the outboard side, to act as jam nuts. I'm not sure if there would be any benefit to doing it the other way, besides making the install slightly easier (no bolts to line up while holding the gearbox in place).
