I actually think it would be easier to learn to tie a noose than it would be to configure the rope in the way you described.
I’m literally describing just winding a rope around a cylinder, then around another cylinder. It is also a way to intentionally set up a suicide, although it might be the least likely way that he died.
Of course if he was really drunk or under the influence of some other drug it is also possible that something led to him wrapping rope around his neck and choking out. Or he had the rope around his neck, but died from some other means like an overdoes. There are dozens of things that could accidentally lead to death with a rope looped around the neck that are more likely that intentional suicide.
