Yes. The snapshot is a frozen image of the file system at the time it
is taken, sharing all the data on the file system. When you delete
data from the file system that is in the snapshot, it isn't deleted
from the snapshot, so the disk space isn't really freed. It won't be
counted as "used" by the file system any more, so the file system will
use less space. Instead, the space will be counted as "used" by the
(or a, if it's in more than one) snapshot, so the total space used
won't change.
The solution is to delete a snapshot, file system, or zvol.
