MX/MPC licensing

I'm looking into getting a MX10003 pair for SP edge. If i were to get an MX10003-LC2103-R MPC which straight comes with R mode license, what does that exactly mean for built-in 6xQSFP and for the 12xQSFP28 with an additional MIC (JNP-MIC1)?

Does that mean that only the 6xQSFP ports are R mode enabled, and for additional ports on the MIC one would need an additional 2x license S-10K3-ADD6-R for the MIC ports to get R enabled as well? How do the MIC ports without the S-10K3-ADD6-R license behave in that case, are they deactivated completely until a IR-mode 6port extension is enabled that matches the IR-mode from the MPC?

Thanks in advance!
