hook in a loop

[jeffc]

I'm really going to show my ignorance now but can someone explain the 'hook in a loop'
I've seen it discussed on several forums but have not seen a clear explanation, diagram, theory, uses or the advanatages/disadvantages?

giles cochrane invention require eyed hook basically put line through eye and tie double overhand knot hook moves freely in loop tried it and undecided as giles says anyway fish come into your peg/swim because of what your feeding and not your hook knot !

Has any body used this yet?
What you think of it?
