Partly. But they still assure that there's only a single instance to
work with, which is globally available from everywhere in your scripts.

That's simply because of how PHP works:

init -> request -> response -> done
init -> request -> response -> done
....

To keep data available for several requests you would either need a real
application server:

init
request -> response
request -> response
....
done

which is not yet available for PHP (except for some experimental
projects) or you could have a look at shared memory.
