There is a helper function in wcautil that is usually a tell tale sign you've found the code ::WcaGetComponentToDo(). The old school way (most of serverca uses the old school) is to call WcaIsInstalling()/WcaIsReInstalling()/WcaIsUninstalling() to determine the scheduling. WcaGetComponentToDo() is a nice wrapper that cleans up much of the confusion.
Using conditions to control your CustomAction install/uninstall behaviors is primitive and usually insufficient... but the most visible. Data driven CustomActions that modify machine state via Resources should really use Component states. That matches the design of the Windows Installer.
