All I can say is that it was a VFR RFM, so that would mean it applies to VFR operations.
When you find the RFM with the IF supplement in it then all would be explaned and you can tell us all.
Normally when flying IFR you would not have to look outside except in the takeoff and landing phases of flight, so the VFR limitation would probably not apply (my opinion) but YOU better check.
