Sounds like it accomplishes basically the same thing, yes. (Only see below)

I think it should be written down somewhere, preferably in a place that is changed based on community involvement (rather than simply the STLS FAQ) in order to keep people from worrying that listing their addresses might trigger an audit.

Note that this applies to all listing services, but *particularly* to STLS, as the listing on STLS is a direct statement TO ARIN that the org thinks it can use its address space more efficiently (which an indirect statement, as on eBay, or a hidden statement, as via a 3rd party soliciting bids does not)

ARIN has repeatedly made clear that the STLS is completely optional, which I believe is the right way to approach it.  I don't believe we should be giving the STLS preferential treatment in the transfer policy in any way.

Interesting point of debate. I wrote this to give STLS an advantage over other listing services because I believe that a single marketplace leads to a more efficient market, particularly in the case where there are so few transactions taking place.

This also plays well into the alternative idea that you'd sell them on eBay perhaps but only *after* both signaling your intent to do so to ARIN (by listing on STLS) and at the same time receiving certification that ARIN really believes the addresses are yours to transfer.

It is in ARIN's best interest to know about transactions BEFORE they take place. Granting immunity would be one of the incentives for telling ARIN directly.
