I would not believe it if I had not had a manager like that
I worked for a MSP where the if one of us messed up it was all about how we as a team avoid doing it again. I could have wiped customer data and the boss would have stood by his team. His name was on the company so it was his issue to fix and his mistake, helped by the fact if something went wrong he had engineers like me who would not stop working till things were sorted. I saw him give big refunds to customers for things that were not our fault, just to make sure everyone was happy and got a fair deal.
The only time he was truly angry was when we had an engineer send a email to others in the team taking the piss out of one of the junior engineers for his ADHD. The engineer was out the building by the end of the day and told he was lucky to be being paid his notice.
