Exactly. I think it tells what's going on, while letting us know Surtur will have an influence over the plot of this film.
A villain is talked about, and given what we know of this movie, what it is based off of, what we know of the simonson run, I think this synopsis can be easily read as Malekith leads an army against the 9 realms, thor goes on an adventure to stop malekith, while Surtur pulls the strings, setting up an attack on Odin. That's what I made out of it. Read it simply. A synopsis is not going to have deep parts and subtly. It's going to be short, to the point, and going to get the reader interested in the film.
