Vaccines aren't 100% effective. I'm not sure what the effectiveness of the hpv vaccine is, but if it was 95% effective (totally made up number, i dont know what the real one is), then there is a 1 in 20 chance it wont work for someone. If both of you have the vaccine then the chance of both failing would go down to 1 in 400. That seems worthwhile to me, given there is basically no downside. (I guess this doesn't account for the affects of herd immunity)
