i think yes it should preserve the first and drop the second one i.e. drop the smaller values – Akash Sethi Feb 22 '17 at 05:44

DropDuplicate method preserves the first Element and removing the others.
So yes , on descending sort only the largest(based on sort) will be preserved and others removed.
