It's still surprising (and undocumented) that -b returns false when the
value of the style is false. I expected it to return 0 for the same
reason that _call_function returns 0 when the called function returns
non-zero: $? == 0 means retrieving the value succeeded; check $test_var
to see what the value is.
But it's been this way for 15+ years...
