I have read some utter shite in my time but this just might take the award. From the laws of the game just point me to where it can be interpreted as you suggest:
An indirect free kick is awarded if a goalkeeper, inside their penalty area, commits any of the following offences:
- controls the ball with the hand/arm for more than six seconds before releasing it
A goalkeeper is considered to be in control of the ball with the hand(s) when:
- the ball is between the hands or between the hand and any surface (e.g. ground, own body) or by touching it with any part of the hands or arms except if the ball rebounds from the goalkeeper or the goalkeeper has made a save
- holding the ball in the outstretched open hand
- bouncing it on the ground or throwing it in the air
