I LOVE the poetry used in Beyond

I wonder though, since the authors of some of the poetry contained in Beyond sometimes use "free licence" with their writings, how does this writing (poetry) translate as great writing for the students to copy?
For example, I see that the authors sometimes use no punctuation, or use caps on each new line of text even though a new sentence or thought is not being expressed.
I thought that the idea (or at least a partial idea) was to expose the student to grammatically correct passages or sentences.
I am by no means an English expert and I know that HOD has perfect reasoning behind this. I just wish to seek this understanding as we make our way through Beyond.
Thank you so much for helping me to understand.
