Okay, I missed "The mouse will be anchored to that position" part. I really disagree with this part of the proposal. Thanks for pointing it out.
However, the comment about the cursor moving to the centre of the screen is an implementation detail. At least on Windows, you need to centre the mouse cursor for something like this because the OS won't (easily) give you actual virtual coordinates.
