Actually, as far as I know this only works from person to person clicking links and not yourself clicking the links.
Say for example I click some Mistyreed Sandals of the Owl and you click a Carving Knife of Holy Wrath (Yarr, I have an item of Holy Wrath from the ol' days <3). Anyway, then a link is sent into the trade channel. The link I get will show [Item] with the properties of 'of the Owl'. Then the item in trade you click will show [Item] with the properties of 'of Holy Wrath'.
Edit: To further explain it, if you see [Felsteel Whisper Knives] with a Mongoose enchant on it is because the last link you browsed had a Mongoose enchant on it.
The same goes for every item. The special properties from 'of the Owl' items and enchants seem to cache itself in links.
