Forum:Yubel and others, timing dilemma

Hey duelists, I really would like to get this question answered. I'm a bit confused about how the timing works for certain cards. On Yubel's card tips page Card Tips:Yubel i found this:

However, cards such as "Hate Buster", "Thunder Crash", and "Generation Shift" cannot Trigger Yubel's effect, as Yubel would miss the timing, because Yubel's destruction would not be the last thing that happens.

The info listed on the "miss the timing" page supports this even further. However there are plenty other card rulings that completely go against this. This was found on Night Assailant's card rulings page Card Rulings:Night Assailant:

* "Night Assailant's" effect activates when sent to the Graveyard by "Morphing Jar" or "Card Destruction".[1]

* "Night Assailant's" effect activates when sent to the Graveyard for a Ritual Summon.[1]

* When "Night Assailant" is sent to the Graveyard by the effect of "Last Turn", FIRST resolve "Last Turn's" effect of sending all cards on the field and in the hands to the Graveyard, SECOND activate and resolve the effect of "Night Assailant", and THIRD Special Summon a monster by the effect of "Last Turn".[1]

There are tons more too! so I'd really appreciate it if this could all be cleared up, thx.
