Do red and blue buffs give 2 stacks for devourer?

Confused by what Patch notes in 6.5 says.

"Enchantment: Devourer Rift Herald grants less stacks.

It’s that time of year again, when auto-attackers rampage through the jungle, farming until the 20-minute mark and coming out stronger than the rest of their team. When we first released Devourer, we gave devourer junglers extra stacks for two types of monsters. **Contested objectives - like Red Buff, Blue Buff, and Scuttle Crab - became worth two stacks, **while team objectives like Dragon and Baron yielded five stacks. When we added Rift Herald to the game, we tagged it as an epic monster. Rift Herald, while contested, has not consistently drawn team pressure, and as such we’re aligning its stack reward with other contested objectives."

Does this mean they are supposed to give 2 stacks but it's a bug that makes them not?
