Basing myself on actual design, they rarely create a trait that does more than one thing.
It could be like Nascent Chaos and mix in both Shotgun and Buzzsaw but I doubt it would also add the second charge. Also, you have Nascent Chaos trait and Inner Chaos action to learn separatlyqqqq.
We also have no confirmation that those actions needs Reassemble, it's possible but not confirmed.
What makes me think (and hope) that it's not the case are the 20 extra battery.
What's the point of giving another charge on Reassemble if you will still use it on the same action? At top, if you drift Drill, you could lose 1 or 2 reassemble per pull. Not something worth giving a charge.
No, it's based on if we still learn something every 2 levels.
If MCH gets Shotgun, Rea 2nd charge, Buzzsaw and Queen finisher, then something is missing.
