The Future Barry left. He wasn't affected by any of the changes. Well, other than seeing season 1 ending Barry. So, that won't happen now. The Barry that faded away, from Thawne showing back up, was the season 2 ending Barry.

But it begs the question, did Thawne go back again to 2000 to replace Wells? He has to, considering him remnant dissapeared. But at that point, why would he? From his point of view, he doesn't need to do that. Last we see of him, is in the present.

If the timeline couldn't be changed, time remnants would actually make sense. But since time can be changed, time remnants make zero sense. They change due to how the plot asks for it.
