Surprising lostpointercapture event test 11.1

Hi folks.

I investigated test 11.1 and would like to inform something in this test,
which confusing me.
pointerevent_lostpointercapture_is_first-manual.html

Test 11.1 have strange expected behavior and dis-corresponding description.

Description:
Press and hold left mouse button over "Set Capture" button.
"gotpointercapture" should be logged inside of the black rectangle
Release left mouse button. "lostpointercapture" should be logged inside of
the black rectangle

After release mouse button browser should fire such sequence of events:
pointerup and lostpointercapture events.
But test checks that lostpointercapture event should be asynchronous. This
set up in following:

on_event(captureButton, 'pointerdown', function(e) {
    if(isPointerCapture == false) {
        isPointerCapture = true;
        captureButton.value = 'Release Capture';
        sPointerCapture(e);
        pointerupGot = false;
    }
    else {
        rPointerCapture(e);
        setTimeout(function() {
            isAsync = true;
        });
    }
});

This can be executing, if we second time put mouse on button (first mouse
should be stay on button )
Other words, we can run test only with touch devices (because we should
have ability to put down on button twice).
And description of test has very otherwise description of action, which
user should be doing.
Other words, if user will doing what is in description, test always were
failed on all browsers.

I can assume that current version of test is incorrect, and test should be
changes.

Please, let me know your opinion.

Thanks, Maksim Lebedev.
