I wouldn't say that the 3 stated reasons for being more likely to get disfellowshipped is a deliberate distortion as I've heard many elders actually read into this direction from the update as just that, and under exceptional circumstances if someone has committed any other sin and after repeated loving attempts to change his mind he does not show repentance then yes he will be disfellowshipped for other sins.
This is how I'm reading into the new direction:
1. Slow down disfellowshipping by trying to make more reprovals for other sins. If this isn't possible after repeated attempts then disfellowship.
2. Quickly act to disfellowship if the publisher has turned to apostasy, is exposed for csa or is scheming to end a marriage.
