Apologies for the slow reply. Using VS2007 and VS2013 I am seeing a different result. I have added the following very simple test case to a .cpp file:
class testCreatingInstances { };
void testGeneralCode()
{
testCreatingInstances *instanceOne{};
testCreatingInstances *instanceTwo{}, *instanceThree{}, *instanceFour{};
}
All 4 variables are shown in the same colour by VA, the colour I have set for local variables. I have local variables in bold turned on.

If you place the caret into "m_CheckInstitute" and "m_CheckService" in turn, what is shown in the VA definition field? This is the right hand side of the two fields VA shows, normally at the top of the editor.
For my sample code I am seeing:
testCreatingInstances *instanceTwo
testCreatingInstances * instanceThree
which seems reasonable and correct.
