Bounds.Contains - how it works?

Hi! I do not get it:

networkBounds.Contains( position )
Debug.Log(networkBounds.ToString());
Debug.Log(position.ToString());

returns false;

Debug info:

How come I get false? Position is exactly as networkBounds center.
Why it returns false??

You can’t have negative extents. What are you trying to represent, and how did you actually get that Vector3??

Hmmm, so negative extent is the problem? Thanks! Now I know where should I look for the problem.
