@mmonstra, i agree with some you said. It would be better if they make more chapthers on each story to make it more 'explicit', since this is an anthalogy after all, you can't expect a full flesh thought out story (which is ashame). Each story had it's own potential, and i would like to see more...
I feel not many people accept Poly in terms of stories, and it can cause major backlash so not many mangaka has done stories like this, overall a nice suprise.
