The example in the docs matches an older version of squashfs-mount (v0.4) that is installed on Hohgant, Balfrin, Pilatus and Eiger. The new syntax was introduced with v0.5, which is only installed on Clariden.
Maybe the docs should reflect this, by describing both v0.4 and v0.5.
You could use tabs feature to implement this:
