There is no such thing as linear tracking with normal mice. You get
movement deltas, and the size of those deltas depend on how fast you
move: the faster you move, the larger each delta gets, and the less
precision you get.
On a touch screen that means that if you lift your stylus and put it down
again somewhere else, it just looks as if you managed to move the mouse
far too fast for the mouse to transmit any deltas in between.
So to an application, there is not difference.

You do a continous movement from one window to the other. But you will
still generate a mouse click event wherever you place your finger or
stylus on the touchpad. Thats just the way it works on every system I've
ever seen that use touch.
If you don't want anything to catch your click, you just have to press
somewhere in the window where nothing will happen except for the focus
change.
