I thought the OP meant that since most of the time startups want you to sell you on taking less in salary in lieu of options it makes sense to start vesting those options immediately. I didn't take it to mean that they didn't intend to stay for at least a year. Looking at it that way I think it does make sense. The lower salary take place immediately.
