Here's the text from the rulebook. Bold part is why I think they decided no TD.
11.7 TAKEDOWN: awarded to the wrestler who takes his opponent to the mat with control and the defensive wrestler hits 3 points of contact (head, hands, elbows, and knees). All takedowns are worth two points. To achieve a takedown the offensive wrestler must:
Pass behind their opponent from a par terre position.
Take their opponent down to the mat from a standing position and pass behind their opponent's hips.
Gain control of one or both legs of his or her opponent while that wrestler is on his or her hip or in a sitting position on his or her backside while the plane of the defensive wrestler’s back is less than 90 degrees towards the mat all while the defensive wrestler plants their hand or elbow on the mat.
Lock up a cradle position while the defensive wrestler does not actively hold the leg of the offensive wrestler. In this case, it is not necessary to pass behind the hips of the defensive wrestler.
Examples that are not takedowns - if the offensive wrestler spins behind his or her opponent and the defensive wrestler attains a quadpod position, it is not considered a takedown until the defensive wrestler’s head, elbow or knee contact the mat. The “Merkle” position, where one wrestler has his/her leg encircled inside the leg of his or her opponent while in par terre and has the head and arm of their opponent locked at the same time is not considered a takedown in international wrestling because the offensive wrestler has not passed behind the defensive wrestler. The hips of the defensive athlete must be covered for the offensive wrestler to achieve a takedown.
