kernel-package and moving the old vmlinuz

[Shaul Karl <shaulka@bezeqint.net>]

kernel-package is not behaving the way I expected it with regard to 
moving the old vmlinuz to vmlinuz.old.
Can you help identifying what am I doing wrong?

The point is that I had
     /vmlinuz -> /boot/vmlinuz-2.2.20 and 
     /vmlinuz.old -> /boot/vmlinuz-2.2.19pre17,
where the 2.2.20 was installed from kernel-image-2.2.20_custom.1.0_i386.
deb.
Next I installed kernel-image-2.2.20_custom.2.0_i386.deb and got both 
vmlinuz and vmlinuz.old pointing to /boot/vmlinuz-2.2.20. Yet 
/usr/share/doc/kernel-package/README.gz states that

     Normally, that is only done if the version of the new image
     differs from the old one

Why then I got both vmlinuz and vmlinuz.old pointing to the same kernel 
image?
