Let's forget what we have already invested in the idea that one event can standardize another; uniform interpretation is a claim far too strong to be tenable.
The fact that a healing precedes a teaching does not imply an unconditional standardization of its understanding; the meaning of a teaching is always conditional on the context and the audience.
If the healing event was perceived differently by various groups, for example as a threat by certain religious leaders, it would only amplify the divergence of interpretation of the subsequent teaching.
The ASIC would never consider that a new compliance directive is standardized by a previous scandal, as each element is evaluated for its own implications on the market and stakeholders.
