[Elecraft] K3 - Diversity Reception, Matched Roofing Filters

I am finishing up my K3/100 kit (all 8 pole roofing filters, no sub rcvr), and already looking over the fence.
 
Am I correct in my understanding that for diversity reception with the KRX3, and using all 8 pole roofing filters (same 8 pole BW in same slots for main and sub boards), that matching of filters is unnecessary due to the inherent 8 pole filter zero offset?  Conversely, matching of filters for diversity only applies if one uses offset 5 pole filters?  Thanks.
