I actually think your analysis here ^ is incorrect based on the text of the FIFA Circular.
The FIFA Circular states the following: "
The offence is committed by the player in attempting to circumvent both the text and the spirit of Law 12, and the referee must only be convinced that this was the player’s motive."
I am now going to copy that text again, with formatting added: "
The offence is committed by the player in attempting to circumvent both the text and the spirit of Law 12, and the referee must only be convinced that this was the player’s motive."
The part underlined above, "the offence", refers to circumvention by a trick.
The part in bold above states that the offence of circumvention by a trick requires an attempt to circumvent
both:
- the text of Law 12 - which, as you have put it, "doesn't allow the keeper to use their hands if the ball is kicked" to them by a teammate; and
- the spirit of Law 12 - which, as you have put it, is "about time-wasting".
In summary, according to the circular, for the offence to have occurred, the trick must be an attempt to circumvent
both points 1 and 2 above.
In the scenario I described, the trick had the first component, since it was an attempt to circumvent the text of Law 12. However, it did not have the second component, since the purpose was not about time-wasting, but was about allowing the goalkeeper to take control of the ball under pressure. Therefore, it didn't meet the test set out in the circular, and didn't constitute an offence.
