I wonder if the OM-1 II's AF works similar to the Sony and if you can set the OM up similar to the Sony if it does.

Probably not. The video suggests that when subject detection is on, the Sony A1 II looks exclusively for eyes and/or faces. Thus, the subject detection fails when the head of a human subject is down and the face is not visible. This is actually rather counterintuitive. I find the logic of turning subject detection off for subject detection confusing, yet the mentality of the Japanese people is distinctly different from that of the Westerners (this is not a critical comment, and no offence is meant).
According to the OM-1 II manual, when the camera detects people, "It tracks focus on such elements as the face, head, eyes, and upper body."
For Dogs&Cats: "The camera detects cats, dogs, and similar animals. It tracks focus on such
elements as the head or eyes."
This suggests that when the face is not visible (and so are the eyes), the subject is still detected as long as the head and/or upper body are recognizable.

It sounds similar to Sony in these cases:

i seem to recall numerous different camera manufacturer's marketing 'touting' how well the subject tracking stays on people/faces even when the person turns completely away from the camera and the eyes/face is temporarily not visible to the camera.
it's strange to me that this video suggests, and seems to prove, that it's better to disable subject tracking when the eyes/face are temporarily not in the camera's view.
