pinning being called consistently?

In the past, pinning required contact with a field element like the field border or field objects. Here is an example from 2012:

[G29]
An Alliance may not pin an opponent Robot that is in contact with a Court border, Fender, Barrier or Bridge for more than 5 seconds. A Robot will be considered pinned until the Robots have separated by at least 6 feet. The pinning Robot(s) must then wait for at least 3 seconds before attempting to pin the same Robot again. Pinning is transitory through other objects. Violation: Technical-Foul

This year the blue box states that if the robot cannot move, it is pinned. It is still a bit hazy. For instance, if you are T-boned, and can move in an arc a few feet forward and back, but cannot escape, are you pinned? How much movement is required to not be pinned?

Clarification is needed.
