Yep. And FLX90 is actually lucky to have an MBAFF with only progressive frames inside. I too generally encode progressive contents as progressive flagged as interlaced, however some of my colleagues duplicate 25fps progressive to 50 progressive, divide in fields and make a "truly" interlaced content 25i.
It's not very likely to find official releases encoded that way, but it can happen...
