Lex Luger at Summerslam 95

Was there a point to Lex interfering in the Diesel-Mabel Summerslam match?  Did Lex know when he was there that he was off to WCW the next week?  What were the WWF plans for Lex following Summerslam? 

Yes, Lex definitely knew he was leaving for WCW at the time.  There didn't appear to be much of a plan for him beyond “Bulldog turns on him”, which is probably why he wanted out of the company so badly.
