Not an electrician, but I believe connecting the disconnect to the neg terminal is a safety measure. If you have the disconnect on the positive, and you touch it to anything on the trailer (which would still be grounded to the battery) you could complete the circuit resulting in a dangerous situation (i.e. if you were wearing a watch, which touched the disconnect and trailer, you just put yourself inline of the circuit). Same reason they always say to disconnect the negative terminal to any car battery first. All this said, if the disconnect is well shielded, etc there would obviously be less chance of a connection occurring.
