See my reply to my own post below...I was interested in seeing the difference between the volume license build and the Office 365 build of MS Office 2016. Was referred to Rich's post. Had read it it and was insightful, but wanted to understand Microsoft's logic in creating this weird installer. I think I get it now and posted my findings below. Basically, I figured out how the com.microsoft.office.licensingV2.plist file is generated during installation in the GUI.
