Why does a transaction get created when executing a“throw” statement as no fuel is used?

So for example, we have the following contract:

contract testThrowContract {
function testThrow() {
throw;
}
}


Once the contract is compiled and mined run the following:

testThrowContract.testThrow({from:eth.accounts[0]});

As the only statement executed is the “throw” and no fuel is used; then why does a transaction in the block get created as no state has changed? I wouldn’t have expected a transaction to be written to the chain in this particular case.

I have included the transaction details in the block below, which shows the zero fuel zero ether transaction.
