I am no expert but it seems logical to me that the chain of evidence is not sequential but follows an opportunistic path. One element might be added which relates to a provable date. Another might arise through a chance event or reference to a situation many years between.
They may be linked or one might cancel out the relevance of the other dictating a change in direction.
Such a situation may have arisen around 4th May 2022 when a definite alteration could be noted in information and emphasis released to MSN.
