What is Profile Configuration doing?

[CLi37]

I do not understand why set profile config below

PXCTouchController::ProfileInfo pInfo;
tc->QueryProfile(&pInfo):
pInfo.config = PXCTouchlessController::ProfileInfo::Configuration_Scroll_Horizontally;
tc->SetProfile(&pInfo);

Note:

Document bug, No PXCTouchlessController::ProfileInfo::Configuration namespace anymore.
pInfo.config = PXCTouchlessController::ProfileInfo::Configuration_Scroll_Horizontally;
