That's not how I read it :
>> The impairments with high compression are not as bad as those for 1080i/25
implies that 1080i25 suffered worse that 1080p50 when you reached the encoder's limits

But not unsurprisingly, the lower number of pixels in 720p resulted in the overload happening at lower output bitrates.
