Almost. The 16 means that all of the entries add up to 16. There are two entries, one for the parent directory and one for the current directory. Each of these directories is using 8 blocks. If this directory was removed only 8 blocks would be recovered. The parent directory would continue to exist and continue to consume the other 8 blocks. You can see the 8 in the original directory listing posted above. Although the user seems to have entered the command "ls -la", we see the result that we would get with "ls -las". I guess an alias or a function is in use providing that s switch.
