Kate aged Derek back to the time BEFORE he had taken an innocent life (Paige, his former girlfriend). Yellow eyes are for werewolves who did not take an innocent life, and blue eyes are for werewolves who did take an innocent life. Actually when he was aged back his eyes were blue so like Peter said "after Paige". I don't remember it being explained but Kate somehow managed to "steal a part of his past" when his eyes turned yellow instead of blue.
