Notes on NACO Obstacle Departure Procedures

What's with these notes about all the obstacles? If I can fly the
take-off minimums and/or fly the ODP (if specified, not in the example
below), does such keep me clear of the noted obstacles? (I think the
answer is yes, but then-- what's the point?) Or do I have to do all
this pythagorea in my head?

Thanks,
