As it would if they were both at the same side of the bed. The stupid bit is parking one at each end of the bed and needing two pickup mechanisms. That removes two times the extruder width from the printable area. If they were stacked at one end of the bed then the pick up does not need duplicating and you only lose one extruder width from the print area.
