No, it is not the case. Does the order in fstab meter ? 
/dev/ad0s3d is already mountrd on /var when md0 bumps in.
>From memory it looks like this:

 % mount
/dev/ad0s3a on / (ufs, local)
devfs on /dev (devfs, local)
/dev/ad0s3f on /tmp (ufs, local, soft-updates)
/dev/ad0s3d on /var (ufs, local, soft-updates)
/dev/ad0s3e on /usr (ufs, local, soft-updates)
/dev/ad0s2d on /home (ufs, local, soft-updates)
/dev/ad0s4 on /vol/it/xp (msdosfs, local, read-only)
/dev/ad1s3d on /vol/it/cur/h (ufs, local, soft-updates)
/dev/ad1s2d on /vol/it/n (ufs, local, soft-updates)
devfs on /var/named/dev (devfs, local)
/dev/md0 on /var (ufs, local, soft-updates)
