Dunno how you managed to find that page, as when I click on your link, it says This page may have moved or is no longer available.

However, on the page http://pages.ebay.com.au/help/policies/listing-multi.html, the ONLY reference to selling on more than one ID said

You are not allowed to have more than one listing of an identical item listed separately by the same seller under another eBay user ID.

Heck of a lot different to your original assertion.
