Uhm... no?

You have to look at this from the POSIX path angle.

"/" is not the same as "/cygdrive/c/cygwin", even if, under the hood,
they resolve to the same Windows path.  For every POSIX path, the mount
flags are taken from the matching fstab entry.  So, take two fstab
entries:

  C:/foo /bar some_fs binary 0 0
  C:/foo /baz some_fs text 0 0=20

If you write to a file under /bar, it will be written in binary mode,
if you write to the exact same file under /baz, it will be written in
text mode:

  $ cd /bar
  $ echo Hallo > blub
  $ od -c blub
  0000000   H   e   l   l   o  \n
  0000006
  [~]$ cd /baz
  [~]$ echo Hello > blub
  [~]$ od -c blub
  0000000   H   e   l   l   o  \r  \n
  0000007

Does this example make it clearer?
