What does mean minimum and minimumWorld in BoundingBox?

I create a simple playground where I move a box by 2.0 to the right and the I get min and minWorld of boundingBox.
Why does it give me the minimumWorld as: -0.5 for X-axes, when actually the minimumWorld should be 1.5?
What do minimum and minimumWorld mean there?


minimum and maximum both is only caculated by the geometry vertexes and dont calculate any transition like rotate or parenting or move

but world minimum and maximum calculate absolute value after all dependensy be applyed
