A) the swarms had gone first, instead of the PCs
B) the swarms hadn't been so piled up that AoE were able to hit all of the swarms.
Most certainly.
Did one more test with KotSF characters at 1st level against 4 swarms (to see how different it would be compared to the DDXP group). It wasn't much different. TPK in quick order.
The biggest factors to the outcome seem to be initiative and knowing your enemy. With the second level party, if the wizard hadn't gotten initiative, and didn't know to use an action point at first opportunity, the fight could easily have gone south.
Next test, 3rd level party vs 6 swarms...
