Yup, Guya. That's one way to interpret the tax code. The most conservative way, which of course, is rarely in the taxpayer's benefit and always in the IRS's.
Of course, there's more than one way to interpret tax code.
The way everyone other tax professional I've chatted with treats a UK superannuation plan is to treat it as an unqualified pension plan, which is the determination the Big Four have come up by following the technical guidance issued with the 2001 US/UK tax treaty in the 2001 Technical Explanations.
As we've both advised you before, MasterBlaster, you can't get a definitive answer online, you get conflicting advice online, you can't rely on Guya or me for the right answer, and you sure as shooting shouldn't rely on the IRS for the right answer. The only advice you can trust is advice you pay for, because then you have recourse (law suit) for any bum steers.
Speaking of bum steers, I'm in Colorado for Thanksgiving. Yesterday I had "bull fries" (look that up on the internet), bison burger, and venison steak. How I miss living in America!
