Do you mean 720P? ABC decided a long time ago that 720P was better for high-motion sports than 1080i, although the resolution is noticeably reduced for non-action scenes. As a result, many of their affiliates went to 720p as their in-house format. Many early HDTVs did not handle format switches smoothly (don't know the situation now), plus there is difficulty in handling varying formats within a station. The result is that most or all stations convert incoming material to their base format and all switching/mixing and final emission is done in that format.
