Copying a NTAG 424 DNA without opening the URI

I'm interested in NTAG424 DNA. 

I understand that the SUN message is based on URL, UID, and counter, so that the generated string is different each time is read. I guess that the server keep trace of each UIDs' counter.

But what if I copy the string of a DNA tag (without actually opening the link), and paste on a new tag?

That string should still be valid, since the server doesn't know it's been read. The copied link would be valid (just the 1st time is read). Is that correct? 


Thank you.
