In poetry everything you say is correct, especially in school/college levels providing you can justify it. I always use stanza structure, line structure and use of punctuation to make points. If that stanza was the entire poem then you could deffinately make a point about why the writer chose to list everything in a single stanza.
An example of what I mean which is very clear is a poem I once studied called 'Mother and distance'.
The poem is about a son moving away from his mother, both physically and mentally. In the poem there is numerous use of the '-' between words. Such as 100-miles. I got the higher graded mark on that section for using the - as a symbol of the son moving away from his mother as it creates distance.
