For scheduled tasks (function calls) that are initialized with add_repeating_timer_us (or add_repeating_timer_ms), updating the Timer value invalidates the scheduled time when the function should be called.
Currently, we update the Pico's hardware timer when we receive a new synchronization signal. To preserve the Pico SDK's ability to reliably scheduled tasks on a particular interval, changing the timer to reflect the new time would mean we would also need to update all of the alarm times.
