Or, alternatively, you may be misinterpreting that page. It appears to be page 20 from Shimano's document DM-GN0001-26, titled "General Operations". That document appears to be a general "how to" setup guide applicable to a wide range of Shimano MTB/Trekking hardware.
Best I can tell, the model number "RD-M786" does not appear in that document - at least, a text search of the document doesn't seem to find it. I'm not sure everything in that document applies equally to each and every item of MTB/Trekking equipment Shimano makes. I'd guess individual item specifications would take precedence.
Trust me it does, and its specific to that derailleur, pretty obvious you haven’t gone to the site yet, but it is on the first page of quite a few, and I didn’t really care to enclose them all. However, for you or anyone else, pretty simple to go to si. shimano.com and enter rd-M786, all the info will come up including the page in my post.
Pretty much answers the OPs inquiry without speculation, and if you play around with the site, covers info on Shimano components well into the 80s.
