Fiddling with the "Flex" Feature - What just happened?

Sorry, not sure where to post this...

Getting a feel for what the "flex" feature can do.

Result:

Section view (it cannot be sectioned right through 0,0,0):

Unexpected, or just odd?  I can see some possible artistic applications maybe.

Thanks,
