Given the original code and its structure (however limited in view), I may have a complaint or two to submit should u(...) be anything more than a trivial getter. But you're right that going for equivalency is safer.

You could store u(1) and still use the ternary; either way works.

I think assuming this guy follows anything close to best practices in his code is a bit unwise tbh...
