[tlhIngan Hol] {net Sov} vs {'e' Sovlu'}

Today I am trying to grasp the difference between {net + verb} and {'e' + verb-lu'} The way I understand it is, for example with "Sov" net Sov = it is common knowledge that 'e' Sovlu' = someone (indefinite) knows that Thus: qama'pu' DIHoHbe' net Sov = It is common knowledge that we don't kill prisoners qama'pu' DIHoHbe' 'e' Sovlu' = It is known / someone knows that we don't kill prisoners Similarly with chaw' : qama'pu' DIHoH net chaw'be' = we are not allowed to kill prisoners qama'pu' DIHoH 'e' chaw'lu'be' = someone does not allow us to kill prisoners Am I getting it right ?
