‘position’ is used to set the object center point position，
Why not when using 3D models？

2

“position” is the position of the object relative to its pivot point, this does not affect the pivot origin.

3

Because his vertices coords at center of pivot. Must be top of pivot into blender, 3ds max. Pivot must be 0,0,0
