Well you can say there is a difference between "computer science" and "software engineering", plus many "universities" are particularly research focused.
A chemistry, physics, or even MechE BS is coming out only at the very beginning of their training, and will require lots of specific on-the-job training if they go into industry. School is about the principles of the field and how to think critically / experimentally. E.g. software debugging requires an understanding of hypothesis testing and isolation before the details of specific tech ever come into play. This is easy to take for granted because many people have that skill naturally, others need to be trained and still never quite get it.
Edit: of course if only 5% of grads are going on to research then maybe the department is confused. A lot of prestigious schools market themselves as research institutions and advertise the undergrad research opportunities etc. If you choose to go there then you know what you're getting into.
