Once youve done that twice you do sort of the same thing backwards but slightly diffrent.

e|-----------------------4-5-5-5-7-7-(b9)10-10-12-12-10----|
B|-------------5-5-5-7-7---------------------------------|
G|-4-4-4-6-6-7-------------------------------------------|
D|-------------------------------------------------------|
A|-------------------------------------------------------|
E|-------------------------------------------------------|

Then you go on to do the first part once more.

e|-(b9)(b9)(b9)7-7-5-4-4-4---------------0---------------------|
B|-------------------7-7-5---------------------0---------|
G|-------------------------7-7-6-7---4-4-4-2-2-----------|
D|-------------------------------------------------------|
