Wouldn't work, because even if they only have one leg each, their torsos would still be normal width and they wouldn't all fit.
Also, that'd be a weird configuration for them to be randomly standing in.
Perhaps their torsos are sideways, so that they can all stand next to each other? I don't see why it's so weird though. I regularly slice off one of my legs and huddle with friends in strange formations at night. It's good exercise.
