There've been stations like that on almost every bridge since the Enterprise D. Not really sure why.
Andrew Probert has stated that Gene Roddenberry originally only wanted the Ops, and Helm stations manned permanently. The tactical station was only to be manned during a red alert, the science, and engineering stations at the back only when they are needed for specific situations. With that in mind the layout of the Enterprise-D makes sense. Obviously someone changed the original idea, probably because it was deemed to be to steril, and the following Star Trek shows then copied that idea.
