After interrupting to hear zimun, may the third person resume his meal without a new blessing (hamotzi)?

BlessingsBirkat Hamazon

Synopsis

All authorities agree the third person who interrupted to respond to zimun may resume eating without a new hamotzi or netilat yadayim, since the interruption was for the purpose of his meal (i.e., the zimun is related to the meal) and his intention to continue eating was maintained.
