The answer here falls to semantics. 1. Yes, it's probably just meant as a figure of speech; in which case, it's acceptable. 2. He said "world" and not "planet". "World" can be defined as a sphere of human influence; in which case, it's also accurate. So, yes, he kept the world from being destroyed.
