At 2:55, and when they show the house again at the end of the video, it looks like half the foundation was pulled up a bit.
This is a common misinterpretation. What you are looking at is the exposed concrete masonry block foundation after the subflooring was obliterated, with the poured concrete garage slab still remaining. Though the ground-level photos above show that much of the block foundation itself was sheared off and shattered to pieces, which is impressive in its own way.
