Yes, this is definitely the case.

mount.8 isn't in my set, but I agree that some text like this would be
useful in the upstream mount.8 page.  I have added a sentence to make this
clear in the mount.2 page:

       MS_NODIRATIME
              Do not update access times for directories on this
              file system.  This flag provides a subset  of  the
              functionality  provided  by  MS_NOATIME;  that is,
              MS_NOATIME implies MS_NODIRATIME.

The change will be in man-pages-2.74.

Cheers,

Michael
