Can I cheat! a steed card and then play another steed sometime later?

I am going to put the official recognition to Mister Ed's answer, saying that he's correct here on this issue. Your interpretation of Andrew's statement is correct, and matches your situation perfectly.

For future reference, should your friends choose to argue with the official stance that you were in the right, there's a detailed treatise on the Cheat! card here.
