Over a year later and still haven't found a solution to this. Anybody out there??
Well, perhaps it indicates broken sequences, perhaps something else that started out as a good idea when AE was still young but has long been forgotten over all the years. In any case, it's probably not much to waste any second thought on...
I wish it was that easy. It's not like something that can just be easily ignored. Often enough I need to input 3D render passes and instead of going through each sequence sepertly to get the square brackets it's easier to select all, and check of "Multiple sequences". If my render doesn't change it's fine, but either I want to play with it in AE before it's fully complete rendering, or I end up needing to add time to the animation. So in that case I have to go and either re-import and replace in the timeline or click on each pass and relink.
I guess from now on I should just import each sequence on it's own. Great pain, but if there's no other way...

If you work with image sequences a lot, check out Lloyd Alverez' Immigration script. It's a huge time saver. And it intelligently recognizes and replaces image sequences.
