well i gota say i am no expert, and all my work technicaly would be homeowner work i guess, but he is definatly doing it alot better and safer than most storys that end in tragedy. usualy the common thing is they fell off the ladder while cutting, atleast with a saddle that is largely eliminated. i have to admit i have done a good bit of cutting off a ladder myself, but always with two lanyards around the tree also, never just standing on the ladder. it realy looks like he thought it out well, and took his time to carefully plan and excecute his tree removal.
