You are right.  I should re-write my point:
You wont expect to go to the same place if you typed in abc.com vs abc.ca
so I dont think you would be too surprised to see that <SC>.com doesnt go to
the same place as <TC>.cn
Which means that TLD dependent SC=TC should not create any problem on a user
expectation stand point.
If you know that typing <SC>.cn and <TC>.cn goes to the same place, it will
happen no matter where you are connected to the network.
But that doesnt mean that <SC>.tld and <TC>.tld must therefore go to the
same place.
There should be no compelling user expectation for this to happen.
