I do not know how it worked long time ago but now documentation for OnAfterDeserialize says “Implement this method to receive a callback after Unity deserializes your object.” – notice this “your object”.
And documentation for ISerializationCallbackReceiver interface says “Care needs to be taken whilst within these callbacks, as Unity’s serializer runs on a different thread to most of the Unity API.”
Sorry for posting obvious things. It is just for clarity.
