There are two classes of JWs - the annointed/chosen ones/those with the heavenly hope and the great crowd/other sheep/those with earthly hope.
This makes it quite difficult to determine as to whether Jesus was giving directions to either the annointed or both classes. But the org does distinguish at times as to the authorities given to them (the annointed) and therefore the directions they may impose on the other sheep.
There is an interesting article about witnessing and who's responsibility it is.
From the Watchtower 2004 3/1 Para 20
The great crowd of other sheep have imitated their anointed brothers. They are aware that their knowledge of God’s purposes brings great responsibility. (Ezekiel 3:17-21) Hence, with the help of Jehovah’s Word and holy spirit, they too keep their oil supply abundant through study and association. And they let their light shine, sharing in the work of preaching and teaching and thus ‘doing business’ along with their anointed brothers. However, anointed Christians are keenly aware that the talents were placed in their hands. They must render an account for the way the Lord’s belongings on earth are administered. Even though they are few in number, they cannot abdicate their responsibility to the great crowd. With this in mind, the faithful and discreet slave continues to take the lead in caring for the King’s business, grateful for the support of devoted members of the great crowd. These recognize the responsibility of their anointed brothers and feel privileged to work under their oversight.
So the annointed are responsible for this work and the other sheep are just imitating them. But it seems that the org is really 'whipping' their slaves into doing as they direct by insisting they serve in the field work, recording their hours, doing it regularly, putting all other things aside and making them feel responsible or face the consequences.
It is no wonder they changed the baptisimal vow by stating they agree to obey the org.
