This has blown my brain. I have never considered doing the diagonal first.
But then, my entire life I mounted a bicycle from the left, right leg over first. It occurred to me I did this so tried to mount my bike from the opposite direction. After finally figuring out how to even move my left left over the bars, I then fell over.
So based purely on this experience, I shall continue to do forward, followed by diagonal.
This, only I do one diagonal and then one straight.
It weirds me out that people conceptualize it as turning a corner, the way OP has here.
