Ah -- "hint of..." -- my mistake!
Yes; I can definitely see how Lovano and Potter differ.
This isn't the case regarding Potter and Brecker. I'm not disputing the parallels you draw, it's just that I haven't listened much to Brecker. I'm generally not a fan of whatever one calls electrified amalgamations of Jazz , Rock, Pop and Funk (as distinct from early "classic Fusion" ala Mahavishnu) and Brecker seems to have recorded an awful lot in that vein. I have heard a few examples of Brecker playing in straight ahead all-acoustic settings and while I admire his "iron" chops and intelligence, I don't find him particularly emotionally engaging. I'm aware that Potter has released some more commercial-sounding recordings but I haven't heard them. The recordings I have heard by him have not left me feeling emotionally unengaged. For one thing, he displays a lyrical bent at times that seems very different from what I've heard so far from Brecker.
I know -- "Ignorance of the Jazz is no excuse" -- I shouldn't be so constrained by my tastes. Although they sound like quite different players to these ears, I'll take your word for it regarding Brecker's influence on Potter.
