OK, but the code with the branch is easier to understand.

That's a really nice example. Thanks.
From the article:
=====
Should you go branchless?
Most of the time, no. Branchless code is harder to read and easier to get wrong. Besides, compilers know a lot of tricks and already do a lot of this work for us.
Only when a profiler points at a hot loop, and the loop contains a branch on unpredictable data this technique can pay off big.
