If somehow something should getting into contact with the positive terminal there could be a short, but with the negative lead disconnected you are safe, unless, of course, something hits both terminals. Disconnecting the ground lead in automotive applications stems from the fact that the whole body/chassis would be at "ground" level so it would be difficult to short anything out.
In my case it made more sense to put the switch where I did as it is out of the way and kinda protected from an accidental disconnect. But I don't think it makes much difference.
