I think it's this:
Leg 1 - Lisa & Michelle are eliminated.
Leg 2 - Dennis & Isabelle are eliminated (possibly via penalty due to customs fast pass).
Leg 3 - Michael & Scott eliminated.
Leg 4 - Shelley & Nici eliminated.
Legs 5/6 - Pair of NEL and Elim.
Legs 7/8 - Pair of NEL and Elim. By the end of Legs 5-8, Tim & Te Jay and Keith & Whitney are eliminated.
Leg 9 - Kym & Alli are eliminated.
Leg 10 - Final 4 in the Philippines.
There is a tendency for racers in their home turf to not win. Frank & Margarita, Tara & Wil, Amani & Marcus, and some teams in the Family Edition. But some do win in their home turf like Josh & Brent and Bates & Anthony.
My guess is that the team who won the Save never got to use it since they were never near the bottom...
