First, please note, that you should ask you Microsoft sales reps about all license-related questions.

Having said that, here is more info about the licensing with Windows Server 2012:
•      All Windows Server editions, purchased via the general channels (like EPP, OEM, OLP, etc.) are licensed for two physical processors regardless of the cores.
•      Windows Server 2012 comes in two editions: Standard and Datacenter; Microsoft dumped the Enterprise edition
•      Windows Server 2012 Standard comes with two licenses for Windows Server 2012 Standard virtual machines – that means, on a single Hyper-V server you could install two Windows Server 2012 Standard virtual servers using the same license; for the next Windows Server 2012 Standard virtual machine you will need a new physical license (example: for 5 virtual machines on a single server, you will need 4 licenses)
•      Windows Server 2012 Datacenter comes with a license for unlimited number virtual machines, but they all must be installed on the same single server where the licensed Windows Server 2012 Datacenter is installed. If you have a powerful server that needs to run many virtual machines, purchasing Datacenter edition could be better solution.

There is something wrong with the way you calculate the virtual machines: the number of virtual machines running on a single server is not limited by the number of cores: the processor resources can be shared between the virtual servers allowing you to have more virtual processors than actual physical cores.

Why do you say that a limit of 4 VM and 2 VMs can be installed?  That is not correct.
