Yes, but the person who tries it for the first time based on your post may not be so lucky. I would never suggest dangerous activity with a chainsaw.
It's all about what one is comfortable with. Bucking rounds, especially BIG rounds, is often easier one handed. Cutting over one's head, even fully extended, is often a necessity.
Know your trees, know your cuts and where they'll hinge and land, know your tool, know your body, know your health and comfort.
