That's right, I know it's potentially a bit confusing, but the end of the bar in the progress tracker does not mean the work is finished by that date, it just means the currently scheduled (and public) work will run up to that date.
CIG typically take some time in January to plan out more work for the next year, so by late Jan or early Feb we should see new tasks appear in the progress tracker reflecting the work planned on those tasks. But even the end of those bars doesn't necessarily mean the work will be complete by then. Just that it hasn't been planned and scheduled beyond the currently-shown end date yet.
