It is not the check or the select.
It is the way the substitution has been implemented. It looks like the code replaces the variable name and not the value.
Which is different from what is written at page 800.
I only hope they won't change the manual to match the feature/bug (warning: new joke)

Doctor: What is wrong?
Patient: My elbow hurts when I do this, what should I do?
Doctor: Quit doing that.
USING is not working the way you want, mainly for the reason you found, the CHECK is being parsed before the variable is substituted. At this point it is time to do something different.
