Context in this case has been boiled down to a few main things, and basically those which are pictured as examples, and those which were mentioned in the guidelines video:

Can it mirror/reflect and still look/be the same?

Can it be seen at small sizes and still look/be the same?

Does it look like a flag, and not a pictogram?

I gave Red Peak 5/5 for Context because the way its designed solves all of those problems. In comparison, either of the Silver Fern designs do not reflect well, you cannot see the detail when it’s small, and it totally looks like a pictogram, hence their low scores.
