Generally, it's best to try and get him back to sleep if possible. If it doesn't work, you can always have some activity time before the next feed. Your routine will look more like EASAE, but that's okay. Tyler was a 30 min napper and I couldn't always get him back to sleep, so that's what our day looked like quite a bit. I often adjusted his feed times slightly so that the next feed wouldn't be due in the middle of a nap, and I always avoided feeding right before a nap, even if it meant having just 5 min of activity time after eating. Does that make sense?
