Conflicting info from TESU for dual degrees??

[ACI]

My son is getting ready to finish his dual CIS/CS degrees at TESU. 

We called academic advising today with some general questions.  The advisor (Dennis) told us something that really threw us.  He said when you graduate these two degrees (CIS/CS), you cannot have any overlapping credits between the two AOS.   He said NONE of the 6 classes in the CIS concentration can overlap with the CS AOS classes.  So, these three classes: (SDC) Computer Science 302 - system analysis, (SDC) Computer Science 303 Database Management, (SDC) Business 303 Management Info Systems cannot be counted both places. I know it was clearly stated here that we could have 3 overlapping classes and these were the suggestions.

He cited this from their website:
"Students who desire to have two different Thomas Edison State University baccalaureate degrees awarded in the same graduation cycle may do so providing 24 credits are different in the second degree's core/area of study. In addition, all requirements for both degrees must be satisfied."

So, he is saying that because the business degree only has 18 AOS credits required, all of them have to be different than the CS degree.  

I am really hoping he is wrong! Thanks for your help!
