TF/Snap Question: Copy at 100% bad?

Hi.

This might be a basic TF/Snap question, but couldn't find any thread that clarify this for me:

We needed to create a copy of a production DB and mount it on another host to do some testing and data extraction, so we decided to create a Snap from the production devs. The array is a VMAX.

This should be a very quick test, but we keep this for some time and now this is the current status of the copy:

There's one particular dev at 76%. Is there a problem if it reaches 100%? or this only means that it changes 100% of the original data and there's no problem as long a the Snap pool doesn't reach 100%?

Thanks!
