I watched the whole process of pulling the pipe, the ROV never went back to even check the empty hole for visible signs of leakage. All it cared about was the pipe assembly. There are only two explanations that I can see.

BP could care less about sea floor leaking.

The sea floor is already leaking and another 200 foot hole wont make much difference.

At any rate someone needs to ask them why they did that.

They pulled the pipe out so that they can cement that section of drill hole. Then they redrill and move down to the last part where they will intercept the main well bore. That was part of the plan all along.
