Catalyst, Perverse Metabolism and Symbiotic Relationship

[Mortarion]

I have some questions about how the rules for Experimental models fit together. Lets start with their signature ability Perverse Metabolism. It says the following:

"Perverse Metabolism: When this model would suffer damage from Poison, it instead Heals an amount equal to the amount of damage it would have suffered."

The way I have interpreted the rule is that it only replaces the damage part of resolving Poison damage. So for example, if a model with this rule has Poison +5 it would Heal 2 in the End Phase instead of suffering 2 damage and then it would lower the value of the Poison condition by 1 (since that part of resolving still remains).

We then have another rules, Catalyst, which says the following:

"Catalyst: Models with Poison that start their Activation within 3 suffer 1 damage from Poison."

I've interpreted this as being completely separate from the resolving of Poison in the End Phase. Therefore, a model with Poision which starts its Activation within 3 of the Catalyst will suffer 1 damage (or Heal 1 if it had Perverse Metabolism) regardless of the value of its Poison condition, the the value will not be lowered after suffering damage (or Healing). 

So far, so good. But then we come to the Symbiotic Relationship rule.

"Symbiotic Relationship: When this model would suffer damage from Poison, it may instead either Heal that amount or have another model in base contact suffer that damage instead. After resolving either, reduce this model's Poison Condition by 2."

In this case, the reduction of the Poison Condition is part of the rule, but it does not say anything about replacing the normal reduction. So if it starts its Activation within range of a Catalyst and want to heal, it would then have to lower the value of its Poison by 2? And does this mean that you resolve Poison in the End Phase, it would lower the value of its Poison by 3 if it wanted to heal? (2 for Symbiotic Relationship and 1 for resolving Poison.)

So, to sum up the questions:
1. Models with Perverse Metabolism still lowers the vaule of their Poison Condition after Healing in the End Phase, correct?
2. When taking damage from Catalyst, you take one damage regardless of the Value of your Poison and do not lower the value of the Condition, correct?
3. If a model with Symbiontic Relationship and Poison starts within range of a Catalyst and wants to Heal, would it lower the value of its Poison Condition by 2?
4. If a model with Symbiontic Relationship resolves Poison in the End Phase and wants to Heal, does it lower the value of its Poison Condition by a total of 3?
