Read the Auto label as a package name, not a schedule
The current checkout confirms four things: one public TikTok link, a quantity of 10, 20, 30 or 40, a displayed total and a receipt email. Everything else about the word Auto is unconfirmed, so plan as if the order is a single delivery to the content behind that link. Do not schedule upcoming uploads around comments you assume will appear, and do not budget for renewals that the checkout never mentions.
If the scope matters to your plan, ask support before paying and keep the written answer with the order reference. When the goal is a thread under one video you choose from your own grid, a different flow may suit you better: buy TikTok comments starts from your public username and then confirms the intended post. Choosing the flow first saves a correction request later, after delivery has already started.
