I actually disagree with this, since the DX roll in question here is not a use of an ability to grapple, and I don't see how ST helps.

This is part of a Ready maneuver, and while I'd mitigate penalties based on having Pinned (big, maybe total removal of penalties), or Grappled (partial removal), your opponent, I'd mostly adjudicate this as something part of a combat maneuver.
