[Prototype]-Does XD randomize drag direction of the element when moving from screen to another?

I have done navigation through artboards with drag (and sometimes also with tap) function. I have known that there is no way to navigate different destinations with drag direction. But now I'm feeling that XD is somehow randomizing the drag direction that user must do to get next artboard (screens in prototype).

I'm having now two screens, where user can change the sizes of elements - in the first screen, upper element is bigger and in the second screen lower element is bigger. It feels natural that if you want upper element bigger, you drag it downwards and again, if you want to get lower element bigger, you drag it upward.

First they were working like this, but after some modifications, the drag direction in both screens are now upward. That could be understanded that as a prototype mistake.

But for a moment, it was even worse: To get upper element bigger, you had to swipe it from right to left and lower element was possible to get bigger with swiping it upward (as it should be)... 

Is there any relations to drag direction, where you place artboards in layout view, how you make connections between screens (from dropdown or by dragging the arrow) or how you can manage the drag direction in XD - or is the function "automized" as auto-animate is too?
