The Pope - Does he tactically ex-communicate?

[ULC]

According to just about everyone, the pope gives one warning, correct? I believe this is assumption is wrong. dead wrong. I was playing the HRE (vanilla/MTW/VI) and contolled italy and denmark. On both occasians I recieved the warning as normal when attacking. He eventually excommed the french, so being a good christian, I attacked france. He promptly dies. IN that same year I get a warning to stop attacking the french. The sicilians then invade venice. Thinking that they were warned, I took the province back, AND WAS WARNED AGAIN BY THE POPE! I am then promptly excommunicated , EVEN AFTER ENDING THE SEIGE.
