Not really my interpretation at all. It really does seem as though Barclay was tossed from assignment to assignment with his former crews giving him favorable reviews to make him seem more enticing for the next ship he's assigned to. Hell, it's what Riker wanted to do with Barclay. Where I work we did something similar years back. There was a guy none of us could tolerate so when we learned of a job opening that would mean a promotion and a transfer, we all recommended him for it just to get rid of him. And he got the job.
