Description:
------------
The link http://il2.php.net/manual/en/ref.com.php states that  OLE is a subset of COM: "There is a subset of COM known as OLE Automation which comprises a set of COM interfaces that allow loose binding to COM objects".

But OLE isn't a subset of COM. OLE2 is a superset of COM - every OLE2 component is a COM component, but the opposite is incorrect.
OLE is a superset of COM, it's "more" than COM.

Saying OLE is a subset of COM is like saying C++ is a subset of C...

Wikipedia: "COM is often used in the software development world as an umbrella term that encompasses the OLE, ActiveX, COM+ and DCOM technologies." Thus OLE Automation can be subset of COM.

It's the same what you say: "every OLE2 component is a COM component" means there are COM components and one of them is OLE2 component.
