In my experience they apply it this way:
- C.O.s and their wives begrudgingly leave the Circuit work to care for a parent (maybe they are secretly relieved though who knows?) because of that scripture.
- It is used by the Elder body to keep someone from being appointed if they dont want the man in the first place. If they DO want him, it is ignored.
- If you are giving ANY financial help whatsoever either locally to the congregation or to Headquarters, this scripture becomes invisible and no one mentions it at all. The Org trumps scripture. Always.
