I think it's a basically positive thing--i think she meant that your query accurately conveyed the synopsis of your story, such that she was able to get the gist of the novel but that it's not a novel she felt connected to such that she's willing to beat the pavement to shop it. Who knows why--maybe she wants fluffier things, less cerebral things, something she can easily soundbyte like "This novel is Romeo and Juliet meets Brazil in a postapocalyptic gay bar" or whatev. She's encouraging you to shop it to other agents, who might connect with it. That's a good thing, despite not being "OMG i love it let me represent you plz!"
