As you said, it can't be a reduction in licensing costs, so if the story told by Cerner is true (remember this is Marketing...), the savings must come from somewhere else. Actually the very last sentence spoken by the Cerner string pupp.., ehm sorry: spokesperson, gives a clue what this could be. He said something like this:
"As our client base has continued to grow by 12% annually, we have been able to increase our number of databases managed by the DBA by 30%." </q>

As the annual growth of the number of databases (12%) is less than the net average productivity growth of a DBA (30%), they probably have laid off a number of DBA's...
Let's do some rough calculations:
First let's assume Total Cost for a DBA is a quarter of a million USD and that for a DBA Team Manager is a third of a million USD. To get an overall cost reduction of 9.5M USD, we should lay off 34 DBA's (= 8.5M USD) and 3 Team Managers (= 1M USD). Now we can calculate DBA-productivity at Cerner expressed as the number of DB's managed per DBA (#DB) as follows:

(1) no. of DBA's before using EM = 2000 / #DB (2) no. of DBA's after introduction of EM = (2000 * 1.12) / (#DB * 1.30)

We've estimated before that 34 DBA's are laid off, so (1) - (2) = 34 or:

(3) (2000 / #DB) - ((2000 * 1.12) / (#DB * 1.30)) = 34

If you do the math correctly from here, you'll get at an initial DBA-productivity of a little over 8 databases per DBA (growing to about 10.5 after introduction of EM), which doesn't seem very high assuming fairly "average" databases...
