I suspect magic. If those big ISP's required reverse DNS of all MTA's, they'd have a horrible problem with millions of false positives. If fixing your reverse zone really did contribute to solving your delivery failures, then it was ONLY a contribution and you have other problems that combined with bad reverse caused the rejects. Proof, ie evidence, would be useful.
