I suspect what he means is that as the 300mm lens is 'standard' for 8x10 he expects the DOF to be similar to a 150mm lens on 4x5, or indeed a 45mm lens on 35mm. But the DOF is for a 300mm lens, a telephoto in smaller formats, there are no 'equivalents', the DOF will be very narrow just as the DOF of a telephoto lens is narrow.
