Indeed, it's not a change of context. Hence it is not covered by 3.2.2 
nor any other current SC. Some form of requiring that the user be 
notified is essential here, as otherwise a user may not have any idea 
that their action actually had any form of effect (and then, depending 
on the specific case, may try to activate the same control a few more 
times, resulting in multiple items being added to the cart, for instance)

Also although in the previous example of a form that filters search 
results (where a user changes a checkbox or similar in a form, and as a 
result the search results below are updated) the change is a "change of 
context" (assuming the search results form a large part of the page, 
rather than just being a tiny section of it), I'm not sure 3.2.2 would 
cover this as it requires "does not automatically cause a change of 
context unless the user has been advised of the behavior before using 
the component" - so a pre-emptive "once you change the filter options 
we'll update the results below" kind of indication, rather than 
requiring a notification after the fact.

And again, changes in page content (substantive enough to be called 
"changes of context" or not) that happen automatically (i.e. without a 
direct user input or focus, so not 3.2.1 nor 3.2.2) also currently don't 
require any form of notification for the user (only the ability to 
pause/stop them if they're distracting)
