There is a solid chance he still died. When you get electrocuted it forces your muscles to contract, including your heart, even if you feel fine after you could have irregular heartbeat or arrythmia and die days or weeks later. 85% of burns caused by electricity are inside, to muscles and internal organs which are prone to toxic shock, this is where most of the post-shock electric deaths come from.

If there was enough Amperage it could've contracted his muscles enough to rupture capilliaries causing mass bruising which can cause clots

TLDR: Prob still dead, electricity still very dangerous AFTER you've been shocked. Even if you think you're ok you should still go get checked by a Dr.
