Are Chase's scapula inbounds?

Are the scapula Chase's supporting points while Feldkamp has Chase on his back in near fall criteria?

It appears, at 13 seconds remaining on the video, Feldkamp MAY have established control with Chase on his back, while Chase scapula MAY barely be in bounds, and Feldkamps left foot clearly on the way out of bounds.

Wrestlers are considered inbounds if the supporting points of either wrestler are inside the boundary lines.
