His first statement that all Cretans are liars is based on a premise that he knows all Cretans. The probability of this is extremely low as there are likely Cretans that have moved from his home who he may not know or cannot verify that they are indeed liars. Therefore his statement that all Cretans are liars are based on a false statement that makes his claim suspect. He may be telling the truth that he perceives because of his limited sample size, but this is not likely a universal truth.
