That's an interesting find.
I've only ever assumed "compressed image" to mean qcow2 (with or without compression in qcow2, both are pretty small compared to raw)
I can imagine that '.zip and .tar.gz' might have applied to raw, which can be quite large, but ultimately, you're probably right and found text that needs updating.
