Sounds to me like what he's saying is that if the withdrawn call was  
truly inadvertant, any conclusion the partner draws from it is not an  
inference at all, being based on no useful information.

For example, a player bids one 1H, says "oops, I didn't mean to make  
that call", TD is called rules that 25A applies, player changes his  
call to 1S. To "infer" that the player has hearts is ludicrous, for  
inferences rest on truth, and there is no truth to the proposition  
that the inadvertent 1H call showed hearts.
