What was Rudi Koertzen thinking? | World Cup 2007 | 1ST SEMI Final

Rudi Koertzen gave two official warnings to Dilhara Fernando for running on the wicket in his first over! What was Rudi thinking? It's normal in cricket for the umpire to be courteous enough to warn the player un officially prior to warnign them the first time. Poor Dilhara Fernando knew that one more warning and that was the end of his bowling spell, this in turn totally demoralized Fernando and broke him down. Would Rudi have pulled a stunt like this in a World Cup Semi if the bowler was Australian? Ponting would have exploded all over him.
