Rewrite or don’t rewrite?

I usually rework drastically whatever i write. Stories i reduce to 2/3 their first-draft wordage; poems i hack, bully and warp into a form completely different from what i started with. Words sidle to the other end of their line, morph into different words, and dematerialise; stanzas shift and swap places; line-breaks jiggle around like ping-pong balls on elastic. And in prose, paragraphs die, occasionally to be reborn but more often never to be seen again; scenes shrink to a single sentence (ooh, alliteration); characters change their clothes, looks, and names. Even twitfix take crafting.

So why is it that my first ‘officially’ published poems (in the third issue of ouroboros) are two that i hardly altered from the original moment they came to me?

What does this say about my writing?
