How do you the advanceed wall jump in assassins creed 2

(PS3 Controls)

After rescuing Rose (or whatever her name is) from the venetian guards, she teaches you the high jump.

Controls are: From hanging from a ledge, hold the high profile button (R1), Move the left analogue stick forwards and press X. Hold O to grab onto the ledge.

(Xbox translation)

The same only translate R1 into RT, (or the other one on that side), X into A, and O into B
