It probably means they (or maybe just RB) were looking to be less hands-on, with the day to day. Somebody else running the writing room. Which is what happened eventually with Manny Coto, after he came aboard contributing a few stories in Season 3. That's what I interpret from "another DS9 experience".
Look at the shear amount of stories that had B&B credits on them in the first two seasons alone.
Maybe just wanted to hear Behr's frank criticisms, after coming to no conclusion reading the passive-aggressive reviews kicking around forums - usually just personal abuse aimed at them. Maybe they genuinely were asking for his help. With nothing to speculate about, I can assume what his response was. But say, middle of Season 2 and the sense of apathy to Trek at the time, I dread to think. If it went along the lines of starting again from scratch, it was their creation and they would have every right to show him the door. Manny Coto based on running his show (Odyssey 5) was probably asked for his opinion. Then went on to fulfill the prequel criteria, doing nothing that threw the other seasons right out the window. Not that I'm suggesting Behr would've done that, given he took over Michael Piller on DS9 and all the dull Bajoran religious saga that dominated earlier years didn't exactly go away. Although that certainly took a back seat for the Dominion and then the Klingons, and more Dominion, before resurfacing towards the end.
Probably how the Temporal Cold War was going to end up. Sidelined for bridge building toward the Federation (Seasons 4 & 5), then the Romulan War runs its course (Season 6) and *BAM* Future Guy shows up again (Season 7). Daniels not showing to help, knowing however Archer deals with him, ends up being what's in his historical records anyway.
