Not quite right... chlorine does wonders... it has more to do with milk jugs not holding up to decomposition as well as pop bottles. For what it's worth, I've used milk jugs for short term, and they work just fine. While I wouldn't want to stock up a hundred gallons of water in milk jugs in a closet and forget about it for six months, I'd much rather have thirty or forty gallons that I regularly inspect than none, if the H2O quits coming out of the tap.

Just my two cents.
