It was this sentence in the btrfs wiki, what confused me, also comments
in the net that btrfs is not giving you RAID with redundant data
(https://btrfs.wiki.kernel.org/index.php/FAQ):
"It is possible with all of the descriptions below, to construct a
RAID-1 array from two or more devices, and have those devices live on
the same physical drive. This configuration does not offer any form of
redundancy for your data."
