How is this any different than the swipe to unlock pattern? If you go to a starbucks and sit down for 20 minutes in a higher seat, you can get the passwords to probably 2-5 phones depending on everyone's security and how crowded it is (I inadvertently memorized 3+ coworkers' unlock patterns because they're so easy to see). If someone has physical access to the user they can probably get into most people's phones (that's just saying people aren't careful enough though).
