It makes more intuitive sense to me to drain the system, cut the hose (so it doesn't go everywhere), then add oil / bleed to remove air. Yes, I realize there is a vaccuum in the hose, but once it's disconnected from the reservoir, it doesn't drain out? I guess not...
If you remove the hose at either end, it WILL get some air into it. You will have to bleed the entire system after your modifications.
