Firstly, that's kind of an uncharitable reading. If I said "I'm going to try and pass an exam" you'd naturally understand me as planning to do the requisite work first. "Backflip" just pattern-matches to 'the sort of thing silly people try to do without training'.

However, that said, I'm being disingenuous. What I really truly meant at the time I typed that was moral-should, not practical-should, which come apart if one isn't a perfect consequentialist. Which I ain't, which is at least partly the point.
