I’m a bit confused about what you’re talking about here. “Had to clarify to me this” has grammar/typo error. Also, I think you meant “seem” instead of “seen.”
Is previous statement referring to this?

Whenever only “Hank” or “Rearden” is used in AS it’s actually a shorthand for “Hank Rearden”, they’re always referring to the specific person which is Hank Rearden.
If so, then at the time of writing:

Oh, obviously “Rearden” could refer to his family members.
I thought there was a mistake in “previous statement.” Now, without checking AS I think it’s likely true.

Really, on the subject we’re on right now though(meta discussion?)
So meta discussion is discussion about discussion. When I was talking about whether I made an error it wasn’t meta discussion. But In these two posts we’re doing meta discussion.
