One thing to point out / add: the only reason it works at all is because his "cheat" is the auto translate function that he got when he arrived, which also translates the ancient runic language that spells are written in and subsequently lets him edit any spell he likes into whatever hyper-specific variant he needs like "turn wood log into plywood plank golems". Somebody else with a create golem spell wouldn't get anywhere trying to replicate this.
