In this case probably because hlyg, the original poster, wanted to try
whether the alteration sits in the first MB of the ISO image:

As we are at it, here is my opinion about the case of full image
copying.

Although the pv command is shorter, it imposes the same main risk as
dd or cp, namely the choice of /dev/sdX when running them under sudo.
For safety reasons i propose:
xorriso-dd-target -with_sudo -plug_test -DO_WRITE \
-image_file debian-live-13.1.0-amd64-standard.iso

Have a nice day :)
