The filter order and oversampling are not related. In my example both the oversampling and the filter order happen to be 8, but you could just as well use a filter order of 8 with 16x oversampling (or whatever other combination suits your purpose).

The DC offset is part of the distortion algorithm, not the oversampling process.
