the rolling tendency is into-turn, not out-of-turn. Hence into-turn aileron would be required
Isn't that bar$e ackwards?
But you are correct, the sideslip is eliminated by rudder in the balanced turn. After blowing some cobwebs off I remembered it is the increased AOA on the down going wing (constant roll rate) that causes the out of turn roll, and therefore requires into turn aileron.
To those voting closure, you don't have to keep coming back to read it, you know. Some of us weird types find aerody interesting.

Trying to explain it makes you remember the bits you forgot (if that makes sense).
