C# Language Design: method group inside `is` operator

I'm interesting in some design choices of C# language. There is a rule in C# spec that allows to use method groups as the expressions of is operator:

class Foo {
  static void Main() { if (Main is Foo) Main(); }
}

Condition above is always false, as the specification says:

7.10.10 The is operator

• If E is a method group or the null literal, of if the type of E is a reference type or a nullable type and the value of E is null, the result is false.

My questions: what is the purpose/point/reason of allowing to use the C# language element with no runtime representation in CLR like method groups inside the such "runtime" operator like is?
