It moves in the other direction: for the standard x-axis it moves strings 
up or down.  Compare

axis() overrides any setting of par(adj).

I am not entirely sure why: my guess is that this is to avoid it being 
picked up when it was intended for something else like text.  Certainly 
sensible values would be axis- and orientation- specific so the global 
setting for the device needs to be ignored, but why any setting in the 
call should be is less clear.  Maybe the thing to do is to introduce an 
argument like 'hadj'.
