I have to say poets use what ever comes to mind!
There is no particular reason for it...
I know when I write my poems, I dont say to myself ok, now I am going to write a poem using a particular form such as internal rhymes for example...What ever I am feeling is what I will write about. What ever order, shape or form that it takes is simply how it will appear on paper.
I think most poets feel the same way. I am simply one of infinity poets.
Hope this helped.
it's mostly for rhythm, like using alliteration in a story. also to make the poem sound more natural, rather than using end rhymes - which can make it sound contrived at times :)

Chanelglit is right, there isn't much of a reason other than suddenly thinking of something and liking the way it sounds, or its meaning. Sometimes the purpose is solely for the rhythm, which is much more likely.
I agree I have only consciously used this once
