I agree it looks weird. They're times are counter intuitive to how we normally write a recipe. My guess is that you're correct assuming 20, 10 and FO which is how I would've written it.
My question would be why boil 2 row for 75 minutes? If I wanted better hop utilization for bittering maybe...but...apparently that's not their reason. I'm guessing this is a "juicy" IPA?
