The examples in the page are utterly inessential and confusing - The back arrow rotating? Why did the arrow spin? Are there things in those directions? Can I move in those directions? No. It's clearly just because it can. It's not meaningful.
The Twitter box that spins, falls halfway, stops in mid-air then fades away when you click it? Saccharine. What is supposed to be happening? Is it "falling?" Why does it stop halfway? Why did it start rotating while it fell?
The vocabulary is all wrong.
A printer icon that gets bigger as it appears? Is it moving toward me? Is it inflatable?
A heart that fades away? Is love lost? What the hell is going on?
How can Google expect to be a design leader when they're luring people with vinegar?
I don't think these examples provide meaning - they merely grab attention as human vision has an irresistible response to movement.
And what's wrong with jump cuts? Do you suppose Hollywood and independent movie makers use them for a reason? How about human eyeballs, why do you suppose they dart around from object to object? And how about walls and doorways in architecture - why are rooms separate from one another?
This is clearly just an attempt to mimic Apple on a superficial layer.
