Question:

Is it Expected that the Mass/Test Assignment Process Updates Account Records Multiple Times in Veeva CRM?

Answer:

This is the expected behaviour. The Mass/Test Assignment process has several steps while it processes the data to update the Territory VoD on the Account records. The updates may be seen by enabling Field History Tracking on the Account object.
