Not if you're finding the seed/frame for your Egg. You need to begin right in front of the Day Care Man to pick up the Egg as soon as the Journal is closed so that you get an accurate frame. I think that's what he is doing. Finding his Egg frame/seed.
Also have a question: does surfing advance frames? Because I have been catching the high level Golduck in the Resort Area after picking up my Egg, but the thing is I verified plenty of times with the coin flip trick, yet the IVs do not match. Do I have an incorrect frame? Maybe?
Whatever happens after you get the egg, with regards to your frame, does not matter. But yes, surfing does it advance it. It is the same as walking on a tile where Pokemon can be captured. But, as I said, that really doesn't matter when you are already holding the egg.
To find the frame, seed with the initial seed you targeted (assume you hit it and verified with flips) and match up the IVs of the egg after you hatch it.
