It had always perplexed me as to some familiarity of Pastor Stephen Chan. Now I know, reminded of the person "Tan Sri Dr. Koh Tsu Koon" after reading a news article. The familiarity is perhaps in more ways than mere facial resemblance. Highly educated and all.
At least I can say this, despite the ability and accuracy of facial recognition by different individuals, a person's look combining with his/her attitute and other acts, does influence our subconscious perception to some extend - causing us to either misjudge or correctly judge any other person we meet.
