These two posts were not by the same author
2nd post has a (you) on the top line
1st post does not – the (you) there is not on the top line, it's adjacent to the ID of a prior post that anon is responding to
I'm bothering to write this out, because I see a lot of confusion on 8chan about correctly interpreting (you) markers.
We all know (you) means that the viewer is the author of a post. But it's critical to understand the difference between the top line (where you means you posted it) and inside the body of a post (where you means one of your earlier posts is being referenced by someone else.)
1st post was someone else (UID 8ec88b)
2nd post has the (you) on the author line (UID b750b5)
Different authors of the two posts
The (you) on the 1st post is inside the body of the message, and is attached to the number of an earlier post that was being referenced
