Your first question has been adequately addressed by Quackciel, so I will primarily address your second question.

The ruling in question comes from the way that Takara-Tomy officially determines how card effects resolve, based on the "place of trigger/activation."

Traditionally, if an effect is triggered, it also activates in that same spot.
 * For example, if Diabride, Natural Pyroxene exists on my field, and my opponent plays Don't Move on her.
 * Don't Move then resolves, putting Diabride down.
 * In this case, Diabride's second has been triggered, realizing she has been affected by Don't Move while she is on the field.
 * There is nothing else that happens, so Diabride now tries to activate her second on the field.
 * Because her place of trigger (field) is the same as her place of activation (field), Diabride successfully activates, damaging the opponent.
 * For clarification purposes, another example would be if Diabride is affected by the opponent's Follow Blindly.
 * In this case, Follow Blindly resolves, banishing Diabride to the Ener Zone.
 * Diabride, now in the Ener Zone, now realizes she has been affected by the opponent's ARTS. She now triggers in the Ener Zone.
 * Nothing else happens, so Diabride now attempts to activate her effect in the Ener Zone.
 * Diabride's place of trigger (Ener Zone) matches with her place of activation (Ener Zone). Diabride successfully activates, damaging the opponent.

However, what is in the rulings example is a much different case. It is best if I illustrated how it works:
 * Your Diabride is affected by your opponent's Eternal Punish.
 * Eternal Punish resolves, causing Diabride's power to become 0. Eternal Punish has now resolved.
 * Diabride, still on the field, realizing she has been affected by your opponent's ARTS, triggers her second.
 * However, due to the "0 power rule," Diabride is subsequently banished due to having 0 power. Again, this is not by Eternal Punish, but by a general rule.
 * Diabride now attempts to activate her effect in the Ener Zone.
 * However, Diabride's place of trigger (field) differs from her place of activation (Ener Zone).
 * Because of this difference, Diabride's effect misfires and does not damage the opponent.

I hope this makes sense.
