I typically focus on less tangible matters like software and electricity, so I might not be as qualified as others to comment on this, but I'll do it anyway.
I have noticed that pulling tends to enforce appropriate alignment, while pushing has a habit of bending things out of the desired line. In the case of this chain tensioning system, the bracket holding the axle won't have a lot to keep it from rotating if you just push on it. If the spot you're pushing on isn't actually aligned with the axle, it will be actively encouraged to rotate out of the way.
