Probably the idea of the Excelsior as the E-B was decided upon when it was decided there would be an E-D. That is, the movies had already toyed with the idea that Kirk would in ST4 move from his old Constitution to the villain ship introduced in ST3, but that idea was dropped. Yet a "lineage of Enterprises" was invented as the backstory of TNG the TV show from its very beginning. The artwork depicting the lineage was there from day one, too, so the choice of E-B was made at some point of the creation process of TNG.
Why would they have to be?
When we see Tom Hardy unconvincingly portray young Picard in an old photograph, we have to grind our teeth and pretend that young Picard looked like that. But when we see an Excelsior class starship flying in formation with the E-D, we don't have to think that our heroes are under attack even though the Excelsior was designed to be a "villain ship" originally. The fact that she was designed to be a menace to Kirk and friends doesn't prevent us from thinking that she, too, could be a hero vessel now.
There's nothing in the artist intent behind the models that would have an effect on the drama itself. Picard never treats his Ready Room model as if it were the Stargazer - no suggestive looks or handwaves when his past assignment is discussed, or when Jack Crusher is, or anything like that. The same lack of significance applies to the Observation Lounge art.

The Ready Room model is the Stargazer, the models on the Observation Lounge wall are previous ships named Enterprise.
