No.

"^~" is not the same as "~^". "~^ /" is not the same as "~ ^/".

Read everything very slowly and carefully. The order of the various
squiggles matters.

No. Read it again.

What way of phrasing it would allow you to understand that one location
is chosen? Perhaps a documentation patch could be provided.

No.

One location is chosen.

The configuration in any other location is irrelevant for this request.

There is no superseding across locations. There is no merging across
locations. There is only the configuration in, and inherited into,
the one location that matters for this request.

After you accept that one location is chosen, then you can start wondering
about what happens when there are nested locations, or when no locations
match, and what happens when there are (e.g. rewrite module) directives
outside of all locations.

But until you accept that one location is chosen, you're unlikely to be
comfortable making new nginx configurations.
