This is not an axiom, but simply a consequence of the definition of Synchronize().

Synchronize submits a procedure for execution by the main thread, and waits till the main thread has processed it.

Nowhere does it state that this will be done immediatly. 
The code in the main thread is responsible for checking at regular intervals if a procedure was scheduled, and if so, execute it.
