Its just that if appVayor is anything like travis sometimes builds get queued up which are irrelevant (docs changes, PRs that have already been changed) and it can be useful to be able to cancel builds sometimes.
Also builds error occasionally and need restarting. Or master changes and you want to test a PR again to see if it works now. (useful when someone breaks master)
