What does scale throughout mean exactly? Just normal scaling using the scale operator?
Are you using a graphics tablet or any special input device?
Does the issue still happen if you start scaling with the mouse pointer away from the center of the object?

All points which you mentioned before do not matter. It is the regular behavior of the program. But it seems wrong.

Do not matter as in it happens in all the cases I mentioned above with any input device?

This is the expected behavior. If you move the cursor to the opposite side while scaling, this will change the sign of the scaling operation and result in the object being flipped upside down.

Why is it closed if it is not solved?

I scaled only on a Y-axis, why is it flipped also on a Z-axis? It is illogical.
If it right why when I scale in minus on a Z-axis it scales only on Z?

That is due to the object's rotation. If you were to apply the rotation, then you would see it flip along the Y-axis. That is how this feature has worked since many version.
