That's the biggest consideration when you're not stone cold into the second barrell. If you pick up a back door nut draw, it's a huge value choice to check behind a very strong hand (like a set or made rag straight) intending on dropping the hammer, because there's a wide gap between the implied odds you'll be getting to hit, or potentially putting bad money in before your hand is made IMO.
In fact, I sometimes find myself not continuing the flop for the same reason. Like say someone limp calls EP, and the board comes out rags and you have a flush draw. I might have reason to believe my opponent has A) a set - B) Nothing - or C) A small pair unimproved which he'll call with anyway. All of these lend favorably to checking behind, and the flopped set lends extremely to this choice.
