Maybe Breed is defining "hip slide" in a very specific way? For example, Jim Hardy in his one plane swing says to not do a hip slide. However, he does advocate what he calls a "bump" of the left hip, which is essentially a lateral move to the left that happens just before the down swing. Kuchar and others who say they don't do a hip slide, clearly have a lateral movement to the left. Is that a hip slide? Maybe it's just how they're defining it?
