In my opinion, no. The above debacle was the (now deleted) indicative example of the 2007 Law 75, and in 2007 you were specifically required to continue the auction in accordance with your non-existent fantasy methods.

I think Law 16 is clear about that: Obviously you did not possess the
information about the agreed meaning of 2D when you made the bid. You
received intelligence about the meaning from the unexpected alert and
the explanation. This is UI, 16B applies. The old 75 A was explaining
this, but it was no additional rule. Still the same.
