Wire.onReceive(hadler) terminated only one time

@vipnoob

Why this function does not call again in this case ?

Because it noticed that you don't want to process further input?

@vipnoob

Should I read all data from the Wire buffer before the next call of the Handler function ?
If yes - why ?

Yes, why not?

If you earn 20 Ruble, why do you want to collect only 19?
