The yellow box descent on page 388 of the Dolomites book is missing some information. The correct description is on page 386 and includes the extra short abseil required.
Descent – For climbs finishing on the summit, head to the west side where you will find an abseil point on a large boulder. Make a short abseil of 20m into the gully between the four towers, then make your way down left (looking down) to reach a large cemented abseil ring. Make a long 50m abseil into the gully between Torre Grande Sud and Torre Grande Nord. Continue down the scree gully on easy ground until you reach a final abseil station where the ground gets steeper. Make a final 25m abseil back down to the ground and the start of Fessura Dimai.
