Why is setting the UUID on a checksummed filesystem so slow, and should I be worried?

I cloned a drive, and now I am trying to change the UUID of the cloned drive. There are various answers on AskUbuntu as to how to do this. I was prompted to run a fresh e2fsck first, which I did. But when I actually ran tune2fs I got this message unexpectedly:

Setting UUID on a checksummed filesystem could take some time.
Proceed anyway (or wait 5 seconds to proceed) ? (y,N)

While I was trying to process what this meant to decide what to do, it went ahead and started. It took a few minutes to complete, but now I am concerned. What is the explanation of why it takes so long? Is this something I should be worried about?
