Yes, this is normal. The falsecolor scale for tensor tree isn't percent of
incident light but instead the raw BSDF value. When the patches are all
different sizes you might have a large patch with relatively low intensity
that would have a large portion of the outgoing flux because of it's size.
Using raw BSDF value was the simplest way that I could come up with to
render the tensor tree BSDF. The raw BSDF value is kinda meaningless, so I
decided not to display anything.

Best,
Andy
