Blender v2.76 Strange object location


I have stumbled upon a strange thing in Blender. It is either a bug or a feature I am currently not aware of.

Two mesh objects parented to the same empty objects.
WellA has position (5.1,-8.6,0), WellB (-2041.85,2043.79,-0.5)
Both have DeltaTransform (0,0,0)

Yet they show at nearly the same position.
WellB thus has incorrect position.

Screenshots & Testcase file attached.
