On hand 1, the principle is that basically in any of these 4th suit likely missfit auctions, that one of the things the 4th suit wants to know is whether the suit is stopped for 3NT. Rather than bids spades, your "expert" should bid NT and not allow the bidding to stop below 3NT with his HCP opposite your reverse.
The 5S bid later on is the worst bid I've ever seen mentioned on this forum !
How does he consider himself to be an expert, he cannot envision anything beyond the 13 cards he holds ? Perhaps he guessed correctly on a 2-way finesse once, and awarded himself the expert title. I put this guy on my enemies list so I couldn't play with him again as PD. (Note I have have one guy on my enemy list, he lists himself as WC and I don't think he's even advanced)
