When to do False Grip Lock Off (R1/iM8)

Hi guys - I think I know the answer, but just want to double check.  Should I be doing the "false grip lock off" for 10sec each arm after each rSPT set?  The program mentions doing it after every SARS set, which presumably is the rSPT as it's the straight arm work...but just wanted to double check...

Cheers!

That and BL work are the SARS components of the course where lock offs are the mobility element.
