Does the person who signed Affidavit gets verification call?

Hi can you please let me know if the person (in my case he is my co worker,not supervisor) who signed Affidavit gets call for verification of my work responsibilities.

For some reason I am not in good terms with him now and from company also cannot get work reference letter.

I am in my final stage now.ACS done and got invite.

Can you please advise me on this .

They may or may not be called. Nobody can guess.
