That is indeed just a regular slider. I forgot they look different on UCP so asking you if it looked the same was an error on my part.

The reason the help page isn't updated is that UCP came out only 6 months ago for new wikis and only some of the older wikis have been migrated so far. So there are still wikis using the old platform. Also, the help pages tend to not get updated very often. So even if all wikis were UCP, it still wouldn't surprise me if the help page was still for the older platform.

That said, UCP does not have a way to add a slider using the visual editor. You will have to use the source editor instead. For that, see here. How you insert a slider using source editor has change extremely little (if at all) so the fact that the help page hasn't been updated should not be a problem when using source editor.
