Seeing as how the only difference between the two is a single rule, I
would hope it's obvious where you should be looking.

In the first list, you're explicitly allowing "NEW" connection to the
"ssh" port in.  In the second list, you're simply allowing traffic for
any already "ESTABLISHED" connections.

Please tell me this makes sense to you.
