"Not to be confused with" is a common English idiom. It has several variants, some of which are:
'should not be confused with'
'as distinct from'
'which is quite different from'
'unlike'
All of these expressions highlight the fact that a particular word, concept or idea that appears before the expression, should not be confused with a similar word, concept or idea that appears after the expression. It is usually used when someone wants to be sure that the people who are reading, or hearing, his/her words do not confuse them with words, or concepts, or ideas that appear to be similar or closely related. e.g.
Patriotism, not be confused with nationalism, can be an important binding force within a country.
