What is the advantage of having this/self pointer mandatory explicit?

Question

What is the advantage of having this/self/me pointer mandatory explicit?

According to OOP theory a method is supposed to operate mainly (only?) on m

Answer 1

Eg would be where member names are same as those passed to method

public void SetScreenTemplate(long screenTemplateID, string screenTemplateName, bool isDefault)
        {
            this.screenTemplateID = screenTemplateID;
            this.screenTemplateName = screenTemplateName;
            this.isDefault = isDefault;
        }
