Function parameter type inference: is this example working as intended?

[Nathan S. via Digitalmars-d-learn]

The below writes "uint". Is this working as intended?

import std.stdio;

auto foo(T = uint)(uint x)
{
    return T.stringof;
}

auto foo(T = ulong)(ulong x)
{
    return T.stringof;
}

void main()
{
    writeln(foo(10L));
}
