Yeah, the only way this layout is accurate and doesn't require any mental adjustment is by mimicking the act of looking at the button board, like in this picture.Courtesy of P & H course book 1 and Paint 3d
It's way less intuitive when viewed from a frontal perspective.
In the vertical orientation, it's akin to observing someone in a playing position in front of the viewer. So, right and left are reversed.
I've never understood the advantage of a layout that requires me to imagine it reversed or to look at it from an angle...but I assume it's just a matter of personal preference and familiarity.
