I think there probably is some truth to that, though I I have not experienced that here. Note that it does say "might". I can tell you that eggs not stored properly, or for longer than three weeks aren't very likely not to hatch. I did an experiment where I set a bunch of peafowl eggs all over three weeks old and only one hatched, but it managed to hatch in 27-28 days.

I don't have a lot of confidence in that, I know the older they get the less likely they are going to hatch but not if they are past the 7 day mark that they would need more time. HUM, I guess we will know because NOW you've got my interest up and I'm going to experiment on that.. SO we will know that answer... LOL
Right now I'm experimenting on how long a duck egg can tolerate being set on a turner in an upright position. I have ALWAYS laid my duck eggs down so this is going to be the first on how well they do. I know they can't make it the entire hatching period because I have tried that on several occasions. but I am wondering how long before they struggle or end up dying when in this upright position. I'm hoping they can hold out until four days before hatching day then I will lay them down but until then, crossing fingers they make it that long.. I have a feeling though the larger they get, the more difficulty it is for them and this could be the reason as to why they do better laying down..
