What "auto" covers on new uploads, and how it differs from a single order

"Auto" describes timing, not reach: once live, the plan applies its quantity to each eligible new public upload from that point on, for the plan's duration. A video already on the account, however well it performed, sits outside the trigger conditions.
That's the difference from ordering likes on one already-published video, a single order against a public target already live. It also differs from an auto views or auto comments plan on the same mechanic β those move the view count or comment thread; this one moves the like count.
