Maybe 1 & 3 could be combined.
I'm not sure I get it either. For example, in HKG:
"Check 3: That your Passport and Boarding Pass match" is done first, followed by security, followed by
"Check 2: (Automatic machine) you are legally entitled to leave" Hong Kong
'Check 3' is repeated by the airline at the gate, but I assume that is the case at SIN as well.
When leaving Schengen countries, they seem to do 3 checks in the order listed above by
lokijuh, but each of the people checking these things are too far apart to see each other.
