They are not talking about manual triggers. afaik, and correct me in I'm wrong, I have to write a commit and push yaml file to the repo to be able to run the pipeline. On srht's builds on the other hand I can submit a yaml file by itself to start a job. That way when setting up the build you don't have to go through the whole edit/commit/push cycle.
