Curious, neither can I (8.1-RELEASE):

(f84104b2)[cyberleo at akisha /tmp/zp]$ truncate -s 256m d1 d2
(f84104b2)[cyberleo at akisha /tmp/zp]$ sudo zpool create pool /tmp/zp/d1
(f84104b2)[cyberleo at akisha /tmp/zp]$ zpool status pool
  pool: pool

        pool          UNAVAIL  missing device
          /tmp/zp/d1  ONLINE

        Additional devices are known to be part of this pool, though their
        exact configuration cannot be determined.

'zpool create' starts over from scratch, and will destroy all data on
the target devices; thus, it warns you if it detects that they are part
of an old pool. You must tell it that you intend to obliterate the old
pool to create a fresh new one. This is intentional.
