Because the ACL set on the file do not match any POSIX permissions. The
presence of extended attributes (like ACL) is indicated by "+" at the end of
POSIX permission byte.

Oh, indeed, you DO have permissions. Else you would not be able to cat it.

And here is the fine, that have no permissions set whatsoever.

Doesn't looks like so...

C:\test>>type sub\d2\test.txt

You can't read it from both places. At least, not until you launch either
console from a superadmin account. And stop referring to console as "DOS box",
that's just wrong.

As a general rule, if you are going to mix Cygwin and native tools, let
windows handle file permissions ("noacl" mount option), and you'll not see
such issues again.
