I dont understand Jousting Steed

By mbm, in 2. AGoT Rules Discussion

Attached character gains Renown.

Challenges: unattached Jousting Steed, then it becomes a character with 2 str, military and power icons. when he is attacking alone, there can be only one defender.

1) after he was unattached, does the attached character keep the renown?

2) why doesnt the card just say that Jousting Steed has "joust"? is there a difference that i am missing?

3) my friend suggested that when you unattach him you get an extra military/power challenge, is it correct?

This completely blows my mind.

We have all read too far into some card effects before. :-) I know I have when I was learning the game.
