Why is CA2214 warning not allowed if the private override method is common?

Question

Given the following class hierarchy:

class Base
{
    protected virtual void Do(int value)
    {
    }
}

class Derived1 : Base
{
    sealed protected override void Do(int value)
    {
        base.Do(value);
    }
}

class Derived2 : Derived1
{
    public Derived2()
    {
        Do(999);
    }
}

... CA2214 code analysis warning is resolved by simply adding the keyword sealedin Derived1.Do(). So far so good.

Now let's do Do()generic:

class Base
{
    protected virtual void Do<T>(T value)
    {
    }
}

class Derived1 : Base
{
    sealed protected override void Do<T>(T value)
    {
        base.Do(value);
    }
}

class Derived2 : Derived1
{
    public Derived2()
    {
        Do(999);
    }
}

Return CA2214. Why?

The warning description refers to the following call stack:

Derived2..ctor()
Base.Do<T>(T):Void

... although the breakpoint Derived1.Do()doesn’t hit just fine.

Note: this happens with both .NET 4.5 and 4.6
