The reason he does that, is because he knows a hell of a lot more about PoE than the average forumgoer. Oh, and he's correct, sooo..

Anyways:

Armour is an additive multiplier (Reduced Damage Taken) but it functions multiplicatively with Increased Damage. The reason for that is because Increased Damage affects Damage Dealt, whereas Armour affects Damage Taken. They affect different values, and as such Increased/Reduced are not additive.

Increased Fire Damage increases Fire Damage Dealt, which is used to determine Fire Damage Taken.
Ignite is based on Fire Damage Taken (not Dealt), and forms a whole new value: Burn Damage. It's an entirely different, new value, and as such it has its own modifiers. It is not additive with whatever other value the Burn Damage is based on, because that would be madness.


In your example, how would Resists be applied? To determine the Burn damage, you use Damage Dealt, which does not factor in Resistances (or flat reductions such as Arctic Armour). However, Burn damage is based on Damage Taken, ie. after Resistances. Additionally, it is multplied by Resists a second time (but flat reductions don't apply twice).

The Proliferate is an exact copy of the 'original', so that ought to be pretty obvious.
