Considering we have yet to see much of any flare activity from this region to provide additional analysis, without computational analysis I don't think we can confidently say how caged it truly is, or isn't.

Due to the Parker Spiral & travel time, the CH rotates ~40° passed CM before connection, giving the impression that's the form of the CH that's currently impacting Earth. This is not the case, meaning change in a CH beyond CM has little to no influence on what Earth sees.

Second, the fast solar wind from a CH that reaches Earth is that from when it is near CM, roughly three days prior to connection, not that of its more westward position.

Although they do change in size, be mindful of perception & angle.
CHs are viewed via the corona, which is the outer most layer of the Sun, thus when looking at a CH from any view point other than dead center, there is a lot of material/plasma that can obstruct the view.
