Guy is an idiot.
I would build a fire and using the black coals, sand and dirt, in a tube or bottle might do it.
I would use the cotton to filter what I could first but not in the method you described.

I think the suggestion to use cotton/T-shirt to filter crappy water
was being mentioned in regard to the tsunami situation...
where the inundation renders building a fire to boil water may not
be possible.
I agree that the methodology doesn’t sound like a great option.
Having watched enough episodes of “I Shouldn’t Be Alive”, I’d likely
go for the “recycling” of bodily fluids before I’d try the “filter
foul water that has bathed dead bodies for a week through T-shirts” method.
