Spider attachment clarification

[Rossref]

Rule G33 says "robots may not grab, grasp, grapple, or attach to any field structure." Am I correct in assuming that applies to the spider leg? Are we not allowed to intentionally grab it for the purpose of scoring?

[GDC]

The Spider Legs are considered part of the field structure, and are covered under Rule <G33>. The Spider Legs may be pushed to one side, from the front, or from the bottom, to stabilize them during the process of hanging a game piece. However, they may not be grasped, held, or severely restrained without violating this rule.
