Yes.
QRecall considers two volumes to be the same if they have the same size and name, or have the same size and creation date. A volume with the same name but a different size or partition creation date is assumed to be a different volume.
Now that you have a "new" volume in the archive, QRecall will add new layers to the new volume. To recall an item before the volume resize, select the other volume.
Once the items from the "old" volume get pushed into the oldest (first) layer, you can delete it by selecting the volume in the drawer and choosing Archive > Delete Item...
The "new" volume doesn't really take up any more space because everything is a duplicate of what was in the "old" volume.
