That doesn't throw an error.

And that's not the expected behavior. It behaves correctly, you select the first return and all after.

Many small steps make a leap. It was really just meant as a minor tips on what you should avoid doing.
Then again using select() can avoid some odd cases like
local _ b = UnitClass'player' and such.
