How to add simultaneously moving touches in Appium iOS if one's duration is longer?

Question

There's a UIView in my app. It receives UITouch-es, and has quite complex logic for their processing. The processing logic depends on UIKit touch interface.

I don't know how to reproduce such case neither with TouchAction, nor with MultiAction. There're 2 touches. touch2 starts later, and lasts shorter:

In the moments t3 and t4 touches move simultaneously, then the touch2 ends, but touch1 still moves.
My current not-working code: https://gist.github.com/gatamar/c7182292a1b54379cc26f3e38c823199

In UIKit, touch events look like this:

touchesBegan: [touch1_t1]
touchesBegan: [touch2_t2]
touchesMoved: [touch1_t3, touch2_t3]
touchesMoved: [touch1_t4, touch2_t4]
touchesEnded: [touch2_t4]
touchesMoved: [touch1_t5]
touchesEnded: [touch1_t5]

Is it possible to achieve this with Appium?

Can MultiAction perform two non-simultaneous touches?

Is there in Python Appium Client more low-level API e.g. Selenium, XCUITest?

Any help would be greatly appreciated.

Okey then. here is an example of using gestures in Java.

PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
Dimension size = driver.manage().window().getSize();
//get your screen size
Point source = new Point(size.getWidth(), size.getHeight());
//this is resolution of your screen 
Sequence pinch = new Sequence(finger, 0);
pinch.addAction(finger.createPointerMove(Duration.ofMillis(0),
                PointerInput.Origin.viewport(), source.x / 2, source.y / 2));
pinch.addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
pinch.addAction(new Pause(finger, Duration.ofMillis(100)));
pinch.addAction(finger.createPointerMove(Duration.ofMillis(600),
                    PointerInput.Origin.viewport(), source.x / 3, source.y / 3));

and then you need to perform that sequense by calling driver.perform(Arrays.asList(pinchAndZoom1)); As you can see, you might modify duration of gesture, play around it and you will understand how it works. Also here is some docs with examples.
