And as I have already stated: I don't believe that should be necessary: If the explanation turns out to be incorrect you shall be heard on a complaint that you because of the incorrect explanation has chosen an unfortunate line of play.
The OP suggested that at least part of the motivation for wanting to hear it from the bidder is that he wishes to achieve his good score through his own skill at playing the hand, and not through the assistance of the TD via score adjustment.
Personally, I think this a specious reason, because after all, if you know that there are two lines of play, and if you choose the right one, you'll get a good score, then if you choose the wrong one because you were misinformed, you will know, now and forever, that if you had not been misinformed, you'd have got it right.
