LRS continuous loop: why?

I can not figure out why a continuous loop system is sometimes used when soloing, it seems to be particularly popular for when the solo climber is going at speed. I've seen Pete's old posts on here, his blog, and some stuff on super topo, I still can't figure it out. Yeah, it's good for tagging up gear, but if I'm not tagging? Okay, I don't need to carry the weight of a beefy haul line, great, but nothing amazing. 

Hopefully someone on here can shed some light on this. 

If you need a haul line, without the continuous loop you would be trailing 3 ropes rather than 2.

I find by stacking my 2 ropes on top of one other joined with a knot in a bucket to feed ropes smoothly.

Errr…it’s really easy to stack your ropes for this and  it’s less shit hanging off you.
