Does this alternative pose photography have a name?

This is a suspended photo. There are many ways to take pictures, but the requirement must be a high-speed shutter. A model who can do this kind of action may be a cool runner or a runaway master, making all kinds of actions, and photography is a snapshot.

Another method is to hang a transparent glass in the scene, and the edge of the glass cleverly overlaps with the scene. A polarizer is added in front of the camera to filter out the reflected light from the glass, and the model lies flat on the glass to be hung.
