Its just that the optical lens can't resolve much more than that 5300 optical limit. The sensor can get more information though - 10000 whatever it is, so you can scan at that and then down-sample and hopefully gain some false detail (which is kind of like real detail, but not really).
This is my meagre understanding of it. The optical dpi is really high already though - I don't think you'd ever need to go over it.
Basically what you said is correct but I'd like to add that oversampling is indeed beneficial. In fact it could be argued that the AD side of things should sample at twice or higher the optical limits. Not sure if there's a direct Nyquist link however.
