Arch images on Docker

I’ve read in several wikis that “Arch Linux on Docker can become problematic when multiple images are created and updated each having different package versions.” but I can’t find what the “problematic” issues are? I’ve generally used ubuntu images in the past and never had issues with updating packages. How is Arch different? I know its a rolling release and updates frequently, but i’m not seeing how that is an issue. Can someone help me understand what the issues may be?

Thanks in advance
