I'd guess that if you're cutting something with a chainsaw underwater, they expect you to be standing on the bottom of the body of water.
It doesn't sound like it's meant to be used in very deep water, since it's intended for cutting through wood:
> The Stanley line of underwater chain saws are designed for cutting all types of wood structures including bridge pilings, pier and dock timbers. All chain saw models include an interlocking safety trigger with hand guard and stainless steel spool and fasteners.

There's a photo of it being used, but it's very unclear what's happening: https://www.stanleyinfrastructure.com/sites/default/files/pr...
