Correct. Connect to for example connect to lemmy.ml and pull their communities so it shows in your communities page locally. Dont have to sync the posts etc. Just the base stats (subs, post, comments. Basically exactly what this is doing. https://lemmyverse.net/communities

note: I hadnt seen that page until after my comment... But im getting a lot of 404's on specific communities, so i have to put in their ! name in search...spam that, click to open the community and subscribe.
