Honestly, I'm having difficulty making head or tail of the discussion. I'm not sure what distinction they are making, and I don't know why the distinction I think they are making is important. It seems to be that, the usual sector de-composition is between the Government and non-Government sector, where Government is the currency issuer (consolidated Treasury and Federal Reserve function) and non-Government is everyone else (all currency users, includes foreign Governments). I think they are saying that within the non-Government sector, distinguishing the household from commercial sector is important, but I don't know why.
Anyone care to enlighten me?
