Satellite is a little different than most clients in the way that it displays notes. Most (all?) other clients I think have Twitter-style "posts" and "posts and replies" feeds. Satellite, rather than separating the feeds, surfaces the whole conversation thread when someone you follow participates. So it's possible that the reason your feed looks different on Satellite compared to another client is that some of the replies from the people you're following are nested inside the conversations that were surfaced.
