What this shows Westinghouse's Innovation Score is 62.4/100 (top 2% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Westinghouse?

Each dot is one of Westinghouse’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Westinghouse’s own 18.7 claims/patent is ABOVE the 15.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
