Jet, as I believe you are an aviation mechanic, I am hopeful that you can also help our friend Cole understand that overhaul is a term used commonly throughout aviation -- and, presuming he flies commercially, it's likely with the support of many, many overhauled components, including engines.
That being said, IMO, SEC used the term overhaul for economy of words and nothing else. SA2 is new with little dynamic wear, therefore nothing to overhaul. The fact that strat development is high risk any way you cut it, then changes (including engineering) are a given.
