Fireman, thank you very much for sharing this. Really, you don't know how many people you might have just saved by posting this mistake.
My first year of climbing, I was climbing some big oaks in the woods, taking the tops out of them for a logger that didn't want the big tops busting up the valuble logs in the trunk.
One big red oak, i spiked to the top, tied in with my climbing line (thank goodness!) repelled some, cutting off limbs. I would just do a bottom cut and top cut, letting them pop off.
(similar to what you did on the trunk cut)
there was one particular large heavy limb, I went out on it maybe 6 feet and put my rope lanyard around it.
PUTTING A LANYARD ON FOR A SECOND TIE IN POINT ISN'T ALWAYS SAFER!
anyway, i proceeded to do it just like a regular limb, bottom cut up maybe 1/4 or 1/3rd. then top cut. Well, as we learned here.... yup it split and started to pull me into the limb, I luckily thought fast, pulled the saw out of the cut and swiped my lanyard on purpose relieving me from the pull. I recieved no injury, just a scare. Thank goodness i wasn't just working off of a lanyard. And I was also glad it wasn't a steel core lanyard.
a notch below would have allowed me to cut more of the backwood as it bent downward. or if the limb was large enough in diameter, could have bored in to make my backcut (but still kind of violent).

oh, and yeah, your humor is good. hope you like mine!
