Yeah, I've noticed that with the new Pose.  The Cock goes into your partners thigh.  LOL.  It has to go somewhere. Remember, this is a pose took from the M-F pose so adding a cock, it's going to happen.  I think other than that, the pose has been done very well.  I like it a lot, although I haven't really tried it yet with one of my few Male friends.  
    But, it's a new Pose and I think only you and I have noticed it.   

  As of the other poses I haven't really noticed this intersecting.  Too busy with the action to take notice.   
 
  If it does happen, then I suppose it's what angle the camera is, yes?  Nothing is perfect. I bet there are little "errors" in the other orientations as well.  But, of course that is just a guess.
