Jerricho I sympathise with your frustrations. TCAS pilot training and rules to follow are simple and have not changed much over the last decade. In particular the old adage is to never use TCAS as your own personal radar and only take avoiding action under radar control when in an RA situation.
I guess the pilot concerned was being a little cryptic because he has disregarded the rules and his training and made an a*se of himself. You mention this is not the first time this has happened. I'm surprised in this day and age we are still banging our heads off the wall trying to get the message through.
(From a pilot, not an ATCO).
