Amusing video, titled "how not to climb Pilot Error". On the contrary - considering the leader's nerves and questionable climbing skills, I think they had a good set up:
1. Both wearing helmets
2. Belayer paid out appropriate slack,
3. But was tethered to an anchor to ensure he didn't zipper up to the face while the climber could have taken a ground fall.
Compared to the guys in the photo above, these two did well to protect themselves.
If there hadn't been a bolt - the leader would have had to place gear; and with that amount of nerves, he'd have sensibly backed out of the lead. The bolt may have given him a false boost of confidence.
