I believe that is correct.
In the book, they also took pains to point out the steps he took to try to avoid it happening to the other airlocks after that point too - by actually balancing out their usage a bit more, instead of just always using the same one.
After a few years the orbit will degrade enough that it’ll start to fall back to earth. At that point, the satellite will either burn up completely on re-entry, or partially and the rest will fall to earth.
Either way, each of these satellites will be completely gone from orbit after a few years.
