If you put a tension guage on the tie off line, you would find that the tension is essentially equal to the load divided by whatever advantage exists in the tackle system. (To be accurate into multiple decimal places you would have to figure the weight of rope, hook, and bottom block.)

If you're standing still holding the line, you are equivalent to a heavy object as a tie off. Tree just a heavy object with roots.
