Comment:
Looks like everything is working as expected... the intersection code has
to figure out what to do in the cases where an output coordinate has two
*different* z values (which is what happens in both your input examples).
The answer, longstanding, is that it takes the average of the input Z
values, which is what we're seeing in your examples.
