I know that's what the manufacturers say, and i know that they should know what they're talking about, but i've stored open (folded over and stapled) packets of nottingham in my fridge for as long as 45 days and still successfully brewed w/o making a starter.
And like i said, i still make bread with instant dry yeast that expired in the 90's. It lives in a jar in my freezer. I know the yeast strain is different but it's SAF brand yeast, and i expect that it's preserved with the same process as SAFale and SAFlager dry yeasts.
I know that they say not to store dry yeast in the freezer, I just can't make out why. It works so well for the bread yeast.
