Because CS endows a more fundamental understanding than SE. SE classes are often along the lines of "Here's how you do OOP in Java", whereas CS classes are more along the lines of "Here's how you formalize OO semantics and then implement the semantics at a low level." The latter approach is generally more effective, if more difficult.
