throwin rule clarification

High School rules don't allow re-throws when the ball doesn't enter. FIFA rules require the ball to enter the field or the restart didn't happen. If you suspect a player/team is using this to waste time, give them a warning and if necessary a caution for delaying a restart. And be sure to add the wasted time to the half.

The above is correct. There have been no rule changes which alter the legality of this restart.
The only rule change that the 2005 MEMO made to throw-ins was that opponents have to retreat two yards/meters from the thrower. They cannot stand right in front of him anymore.
