Are you saying there were two nutrient packets in each smack pack? I've heard of this happening, but never seen it myself. Then again, I don't look after I pitch.
Wyeast says it's not necessary to break open the nutrient pack before pitching. It's helpful (gets the yeast going ahead of time), but since you should be making a starter with liquid yeast anyway (although for this beer, two packs is a good pitching rate without a starter according to Mr. Malty, assuming they were fresh that is, if they were older you would have been better with a starter), it doesn't matter.
Point is you would have been fine leaving them alone. As long as you followed proper sanitation cutting open the nutrient packs, you'll still be fine.
