It's a feature. mount -a skips filesystems that are already mounted, so you don't get failures from the attempt to mount a filesystem twice. (mount -A forces all mounts). But your example has another issue, there is no information about the order of mounts, so you may end with filesystems stacked incompletely or even the wrong order. The easiest is probably to declare the filesystem 'noauto' and add a custom rc script that creates and removes your stacked filesystems.
