In 2021, Kyle Carruth shot someone on his porch and used a castle doctrine argument in his defense, and he was not indicted. That would suggest that the porch is considered part of the habitation separate from an attempt to enter. I think the thing you are citing as an authority here is the opinion of a law firm and not a case, and not necessarily a good one (law firms run the gamut from "alcohol addict in a strip mall" to big law).
