Another offside question

[seethinkthendo]

Goal kick by blue team
Red team has last defenders set on half-way line
Keeper in goal area ( only defender on their defending end of field )
Slow blue forward between goal line and half line in attacking end
Keeper with great leg kicks the ball to the blue forward mentioned above

Rule states: "A player shall not be penalized for being in an offside position if the ball is received directly from a goal kick, a corner kick or a throw-in"

Slow blue forward receives ball and scores

Offsides or not?:
