A brief context: I want to deliver the test.

The exact context: Creation of account_id's (first point in an outline).

Question: Do I correctly create account_id in the context of my task. Should I firstly create signatories?

let account_id = Self::multi_account_id(&signatories, 2);

In the documentation of multi_account_id is written:

NOTE: who must be sorted. If it is not, then you'll get the wrong answer.

Can anybody explain why who must be sorted?
