The scene flows better without it (I prefer the scene in V1), but I think it serves the film more to establish the base at this point. Han refers twice to the fact that Finn has worked on the base, so right now it feels like a callback with no origin. It’s a tossup for me, whether to serve the moment or the continuity of the film.
Also, there may be a way to rearrange the scenes in this area of the film for greater effect. If after ‘I need you to tell me all you know’ we cut to Rey’s interrogation, it continues that info-gathering theme. Then, since Kylo’s questions are about Luke’s location, cutting directly back to Leia examining BB-8’s map after Kylo’s temper tantrum continues the Luke theme. The Resistance base scenes continue until ‘The report on the enemy base is coming in’. Having Han and Leia’s talk about Kylo after he has just been unmasked may now have more emotional effect, since we can put a face to their discussion. Then we cut to Hux’s demonstration. The audience learns the capabilities of the weapon just as Leia does, and after this the film progresses as normal.
This has the added benefit of allowing for more time between Finn (presumably) telling Leia the location of the Starkiller and the reconnaissance flight which results in highly detailed scan data.
