The whole approach of the Laws seems to have been to become more and more lenient with infractors. 27B is an example. Certainly in the bidding, the penalties for carelessness have become less. I think if someone opens 1S and his partner announces "12-14", as in the old example on here, then the 1S bidder will pause for thought before correcting it. He will think "why did my partner say that? Ah, I realise now, I must have misbid; I can correct that I think." If that is not pause for thought, I do not know what is, so the TD should rule that it is not "without pause for thought", and we then do not need to involve 73C. However, the WBFLC have decided that this is not regarded as pause for thought either.
There must be some kind of thinking involved when a person realizes he pulled the wrong card. Lamford has pointed out that "pause for thought" is ambiguous; the TD (or the players, if they believe it was a mispull) is/are actually deciding what the thinking was about.
It is possible for the 1S opener to be thinking as Lamford states (replace unintended bid); it is also possible that opener with 5-3-3-2 and in that range would realize he should have opened 1NT (intended bid, not replaceable).
I don't know how to reword "pause for thought" to solve this apparent discrepancy; would rather just trust that the TD's can work out whether the bid was intended or not.
