You need to dd(1) this image beginning with sector 0. I.e. omit the

This is a bit broken in prep, it seems. Usually I edit the disklabel so
the "c" slice coveres the entire disk from sector "0" to the end. Then I
dd(1) the boot image to slice "c".

dd(1) the boot image to sector 0. This will overwrite the MBR partition
table. The image contains its own MBR partition table with a valid boot
partition. Edit this MBR partition table so that the NetBSD partition
starts and ends at the same sectors as before. Don't touch the boot
partition and everything will be fine. No need to reinstall.
