This is when India moved in troops to object to it. Maybe even the Bhutanese objected as they knew India would not agree with it.
The Chinese got greedy and wanted to grab all they could but it all got out. If they had just limited themselves to the Doklam plateau on the east side of the Chumbi valley, then perhaps India would have had to keep quiet following a settlement between China and Bhutan. But it is too late now for that due to their greed. Their salami slicing got bigger for their own good.
I don't think there was any subtlety here.
I think China & Bhutan made a deal India didn't like and India strolled in.
Now to maintain their deal and more importantly - their prestige China need to put up or shut up and lose face.
And the part about not using each other's territory for the detriment of the other in the "friendship" treaty, gives India the Diplomatic cover to do this.
China needs to put up and escalate in an area where they are weak - or lose face with all their neighbors.
The above obviously holds if my original theory holds water.
