I contacted Hodgdon directly regarding this rumor.
The story gets a bit exaggerated here and there but is essentially true.
They don't test it "every year" or even on a predetermined interval but, rather, just whenever they get curious. The powder is stored literally in water, wet. A sample is removed, dried and tested. They told me that it still works fine.
Actually, here is the story, straight from Hodgdon
, numbered page 13 of the PDF, page 19 from the start. There's even a picture of the bottle.
The story says that they test it in a 12ga load and includes a disclaimer NOT to store "modern powder" in water.
