I think you can choose the metering method freely... but you'd better be in Av or M mode! Otherwise, the camera will re-evaluate exposure at every shot (that's how the timer mode work, it's different from "continuous" mode), which may easily end up giving weird results, I suspect.
I thought that in continuous mode, there's no re-evaluation, while in timed mode (even with 0 seconds delay set between shots) there is. I could be wrong, though, or at least it might not apply to all models.
