AD7768 daisy chain  two successive synchronization

We use  2 pcs of AD7767 at daisy chain . (Formatx  01 settings)

START , SYNC_IN and SYNC_OUT pin at datasheet rev.A P24 describes below.


”In a daisy-chained system of AD7768 devices, two successive synchronization pulses must be applied to guarantee that all ADCs are synchronized."


What does "two succeessivesynchronizatoin" mean ?

(does this mean that we should input twice START for  safe because START is asynchronous ?


Please let me know your advice.
