Even this method is not wrong. It provides little security but it isn't wrong that doesn't make sense.
If I was to assert that it was hard to defeat because you would have to cut a thick cable that would be wrong.
Ther is more to Sheldons method & the page it's on that I thought you were taking into account. He recommends, same as you, something that deters the thieves that have only one of the 2 most common tools at hand. His method does both with one lock. Hacksaws are not quick against a good U-lock or a tensioned wheel (w/out deflating, untensioning etc) Bolt cutters are not quick against a good u-lock or a wheel (same reasons) & a failed attempt by a thief learning this lesson would likely damage only your wheel, not your frame or even your lock.
Taken out of context, Sheldon is wrong. In the context of the page that paragraph is lifted from he is not wrong.
