This more subdued communication correctly takes away any hint of potential greenwash from the widely publicized video that the bags might degrade in open air. The shift in emphasis from "compostable" to "natural" represents good green marketing at its best: start with a legitimately greener product and package, and lead with the primary benefits (in this case, great taste and high quality ingredients) -- not with promises of "saving the planet."
