Especially when one clones a drive:
dd if=/dev/hda of=/dev/hde

as I've done. It was a problem with RHL 7.x or so when RH introduced 
labels, and nothing's been done about it that I've noticed.

As far back as, I think it was 1971 with IBM's OS, (I'm referring to my 
memory, not when this started), if the operating systems found two 
volumes[1][2] with the same label[3], it would ask what to do (during 
IPL aka boot) or reject the newer (later).

[1] Disk or tape
[2] One volume, one filesystem.

OS labels (it's z/OS these days) volumes whereas Linux labels 
filesystems. It's not quite the same, to label a disk volume under 
Linux, one would write it to the MBR or other space outside the 
partition/filesystem.
