This is WLP001 - I used it for a Sierra Nevada Pale Ale clone, then washed the yeast and used it for a S.N. Porter clone which has been in primary now for two weeks. WLP001 was one of AHS' recommended yeasts for both of these beers. I've got a huge yeast cake from that Porter, which I'd really hate to waste, so I'm glad I'll be able to reuse that by washing it (after another week or two). My next brew will be a lighter beer than the Porter, and also a few weeks away, otherwise I'd probably just toss the next one right on the yeast cake from the Porter.Sure, assuming you know what flavor profiles to expect from the yeast in question, and they'll work okay with your Pale Ale. Washing the yeast is about as close as we can get to starting over with a new vial/packet of a particular strain without just buying a new one.
