the triggers would have to be from the Home switch to the end of the axis so that once on the home it will be on until it gets to the end of the travel.
As for the advantage, there are many and I will give you a few, firstly on my lathe I have long travels so its a waste to travel away to the end of the axis to reference. The next is the X on the lathe has two tool stations, a front toolpost and a rear turret, I dont want the X axis to travel to one or other extent when referencing as it could cause one or other of the tools to colide with something, so I have it so the turrets/toolpst are approx equidistant from centreline. Another reason is like I have on my machines, Index homing, mine is done in my drives but Ed Gilbert used to sell a board that was capable of Index homing so you needed separate reference switches.
