That's the range at which the yeast works, not the range which necessarily makes the best beer. I have a LOT of experience with that yeast and pitching it at 73, when the heat of fermentation will make the temp rise even more, is not good idea. Not only that, but Westmalle (the origin of the yeast) starts low and lets it rise. You'd think they might even know a bit more than Wyeast. Your choice, though...
FWIW, I do know a bit about Wyeast and how the temp ranges are determined. Look at WY1450.
