Remove or rename debian-live-11.5.0-amd64-xfce.iso before you try to let
xorriso use this name as target for writing.
Other than with the mkisofs emulation, the native command mode does not
automatically truncate the -outdev target to 0 bytes. That's mainly because
-outdev may also be an optical drive which cannot be truncated.
Instead some optical media can be blanked and some can be overwritten.
Data files as targets are considered to be pseudo-drives which behave like
DVD+RW or BD-RE media.
In any case, if the target looks like containing valid data, the xorriso
user has to invalidate those data explicitely. In case of a data file you
may remove or rename it. For all, real and pseudo drives, the data can be
invalidated by
xorriso -outdev "$target" -blank as_needed
This works with CD-RW, DVD-RW, DVD+RW, DVD-RAM, BD-RE, block devices, and
data files. Data files don't shrink in sizei by -blank, but can afterwards
be overwritten from their beginning and may grow.
The -outdev target may only exist with a recognizable ISO 9660 filesystem
if the xorriso run uses it also as -indev for multi-session. In that case,
the ISO 9660 filesystem in the image file or on the medium does not get
truncated but rather expanded by a new session.
(The combination of -indev X -outdev X is normally abbreviated as: -dev X)

Have a nice day :)
