using declaration example doesn't understand variable scopes

[jeffreycoxdoosan]

This comment is incorrect:
// We must declare the variable outside of the using block
// so that it is in scope to be returned.

The example works just fine like this:

    using (var file = new System.IO.StreamWriter("WriteLines2.txt"))
    {
        int skippedLines = 0;
        foreach (string line in lines)
