That certainly was a factor, though there have been reports that Berman found Behr intimidating and tried to minimize their interactions.
This reminds me of a funny story I heard meant to emphasize how little involvement Berman actually had with DS9. I don't know if it's true, but it's amusing all the same. Word is when Stephen Hawking was in studio to film his cameo on TNG, Berman took him on a tour which included a visit to DS9's Promenade set. While they were there, two behind the scenes guys took notice of them. One said "now there's someone I never expected to see on this set." The other replied "yeah, and he brought Professor Hawking with him."
