Yes, TSO's routinely tell people to do whatever they want.

But more importantly, the response of the barcode reader is still fully in control of the TSA. Right now everyone assumes that a 3 on the barcode means LLL, 3 beeps, and expedited screening 100% of the time. This is an assumption made without a full understanding of the system. The barcode reader can still beep once even when a 3 is present in the barcode.
