It doesn't work as after downscale you get 720 25p signal which is not a broadcast standard. This 720 25p signal could be send as PAL format (25p inside 50i), but it's not implemented.
When you interpret as interlaced than 1080i becomes PAL (SD 25i), so it works. The problem is that Premiere may degrade quality a lot as you "pretend" that 1080p is interlaced, so at the end you may loose half of vertical resolution (very common problem in broadcast).
