This is not openssh but ssh from secure.com
ssh: SSH Secure Shell 3.2.0 (non-commercial version) on i686-pc-linux-gnu
From the man page
+x Enable X11 connection forwarding (default). If X11
SECURITY extension is compiled in, treat the client applications as
untrusted (the effects of this depend on your Xserver’s
security policy). See TrustX11Applications in ssh2_config(5) for addi-
tional details.
+X As above, but the client applications are treated as trusted.
-x Disable X11 connection forwarding.
so the +X should have done the same thing as the -Y you specified.
