Therefore pre-HoTting generates no threat on any non-Boss fight up till the point where you engage in combat. Bosses combat-pulse the instance so you're immediately on his table when the tank engages.

that quote are not conflicting. They are actually saying the very same thing.
Renew or any other HoT creates no threat until the tank pulls a mob. As soon as the HoT then ticks, the healer who cast it is flagged for combat and the HoT generates aoe threat to every mob involved in the fight. As this is a small amount, it can be countered by Battle Shout.
