You are right, on the 5 chain engines you only lock one cam on each side with the shorter tool.

Isn't the reason JFP mention for only driver side bank (2) cam to be locked on 5-chain engine because:
to change the IMSB you take only two chain tensioners out - 1 tensioner for the IMS - cam and 1 tensioner for the IMS - crank.
Risk to have the chain to skip a teeth is when there is no tension on the chain.
On the passenger side bank (1), the tensioner will remain in place under tension and the chain should not have a chance to skip there while you work on IMSB.
