I agree with all the reasons mentioned ranging from calculating the vertex position - sharp tip of the arrow (x, y) to the pixel issue (low resolution on older machines) to the right-hand pointing direction.

For all practical purposes, I observed 2 other things.

The first is that English is written left to write. If you ever had the experience of using a different language that starts from right to left, this same arrow feels weird.

And the second is a little activity experience.

1. Arrange the 4 files in a square box, 2 up 2 down

2. Notice that as soon as the sharp point of the arrow touches any file boundary, the arrow can select the file by a pixel difference that you can't with a straight arrow (ease of use)

3. It also takes a constant number of operations (best case scenario) compared to the straight arrow where the algorithm has to decide based on the percentage of how much of the straight arrow shape hovers over another file to select
