While Virtual Groups (specifically Filter Groups) and Profiles do share the "filter criteria" concept, the use of a Profile vs a Virtual Group is of course different and therefore slight differences between the two do exist. 

Notably, Profile filter criteria will leverage a subset of device properties. Specifically, properties that change frequently such as "battery status" will not appear in Profile filter criteria as that would result in the constant installation and uninstallation of device configurations on the device.

In the case of OEM version, it is likely that we at SOTI implemented this property quickly in response to a specific customer request and their particular use case and then later extended it to other use cases such as Profiles as it make sense in both contexts.
