question about the manual

[Frederico R. A. <dev...@gm...>]

I have a question:

---------------
       -c, --changed
              Check the src and destination modified time (see 
--modify-window) prior to performing the operation. If the modified time 
is the same, assume that the files  are
              also  the  same,  and  skip  the operation. Notice that 
unlike rsync, file sizes are not compared. This is because the file size 
is expected to change during the
              encryption (and thus decryption) operation.

---------------

Shouldn't this be 'check if source is newer than destination using the 
file modification time' ?
The modification time will never be the same, since the 
encryption/decryption is possibly done much after the source file has 
changed.

Thank you,
