Looks like the definition of "resolving a ticket" here is "come up with a patch that ensures all tests pass", which does not necessarily include "add a new test", "make sure the patch is actually doing something meaningful", "communicate how this is fixed". Based on my experience and what I saw in the reports in the logs, a solution could be just hallucinating completely useless code -- as long as it doesn't fail a test.
Of course, it is still impressive, and definitely would help with the small bugs that require small fixes, especially for open source projects that have thousands of open issues. But is it going to make a big difference? Probably not yet.
Also, good luck doing that on our poorly written, poorly documented and under tested codebase. By any standard django is a much better codebase than the one I work on every day.
