The same mentality should still apply and I think that's how the refs were thinking.

Back to the rule, pinning is "inhibit[ing] the movement of another ROBOT while in contact with a field element or border". It doesn't say it has to be something rigid; spider legs are certainly field elements. The reason that pinning was not called against the ramp last year was because the ramp was considered part of the floor, not a field element. That may not have been clear in the initial rules, but it was cleared up mid-year and I believe it was called consistently across regionals.
