Again, it is redundant to state that a function object has a [[Call]]
property. It is also redundant to say that the function is an object.
Functions are objects. Change every occurrence of "named constructor
object" to "named constructor".

I suggest rewording that.

[NamedConstructor] function
When a named constructor is called as a function, it creates and
initializes a new object of the interface type.

Question: Do you have any real examples of a NamedConstructor? And if
so, please provide one. TIA.
