Well, I might as well post my (stupid) theory about the poem.

"outside it matters that face of the commands stay constant" - This could refer to editing posts on the forum. Outside of the forum, you can't edit or delete what you say.

"a step forward can take any form" could refer to the general randomness of early ToU, and

"there is no reason at all to be on the edge of caution" could refer to the fact that we don't need to be overly cautious because we can try again as many times as we like...

...but "time passes as one approaches the end" and "before you move, the point is simply to face left" don't seem to fit in to that theory at all...
