Actually, it was shortened as I understood it. They could have always left Woods out of alternate shot which would put undue pressure on his partner (hard to recover from rough, sand, and water).

Nothing was shortened. The format is 4 4-ball and 4 alternate shot matches on Friday and Saturday and then 12 singles on Sunday. Because they didn't finish on Friday they changed the schedule so session 2 and 3 consisted of 6 matches instead of the usual 4. So basically after the first 4-ball matches were played on Friday everyone was be playing from then on, no chance of sitting anyone out.
