No, it doesn't. It's about relevance. Just because, for example, there is a Cunnilingus / クンニリングス on a page, that doesn't mean a gallery has to be tagged with it.
To stick with the example: imagine you're looking for a work tagged with it and you're looking forward to explicit scenes, and then it's only mentioned in 1-2 panels.
That would be disappointing.
Here is a (translated) universal quote from Shirou:
"Yes, 1 to 2 pages are sufficient only if the upload itself has few pages, or if it is an extreme tag such as guro or scat.
Otherwise, it should be about 20% of the pages or a relatively large number of pages in a row. It depends on the total length. For 50 pages, 5 pages with the tag is not enough, but for 20 to 30 pages, it is sufficient."
Otherwise, go to the Discord server and ask one of the old mods.
There are other works by her on the list, but I have no idea when they will be released.

1. blackmail is the main focus in this one
2. she only falls for him at the end
3. it's tagged the same way on e/ex.
There is simply too little to see (One Page) for the latter. I have adjusted your Edit.
