This is a good catch. Two quick observations:
1) Super pedantic point. I don't like the 'repl.' abbreviation in the
'most common implementation' both for the existing hs/sr and for the
newly added logical.
2) This lingo:

Is good, but I would revise it just a bit to emphasize the
subscription nature of logical replication to link the concepts
expressed strongly in the main section. For example:
Logical replication allows the data changes [remove: "from individual
tables to be replicated"] to be published to subscriber nodes. Data
can flow in any direction between nodes on a per-table basis; there is
no concept of a master server. Conflict resolution must be handled
completely by the application. For more information on...
what do you think?
