No point light shadows of Toon objects with 'Env. shadows' enabled on each other

[DriesV]

On Toon objects, when 'Environment shadows' is at default (off), shadows generated by a point light from one object are cast across the other Toon objects.
Why is it that this 'casting of shadows on each other' (don't know a better way to put it ) does not happen when the 'Environment shadows' option is enabled? In that case only self-shadowing is visible. There are no shadows from on object onto another.

Physical light shadows between several objects can give a really nice (graphical) touch. However, a lot of geometry definition is lost without 'Environment shadows'.

Please see attached images as reference.
