GetExpectedLimit?

I’m trying to figure out the difference between these two functions:
http://root.cern.ch/root/html/RooStats__HypoTestInverterResult.html#RooStats__HypoTestInverterResult:GetExpectedLowerLimit
and http://root.cern.ch/root/html/RooStats__HypoTestInverterResult.html#RooStats__HypoTestInverterResult:GetExpectedUpperLimit

They look exactly the same to me. Are there two of them for a reason, or is this just a strange API?

Hi,

GetExpectedLimit is a private function used to implement the public functions, GetExpectedLowerLimit and
Get ExpectedUpperLimit
