DynamoDB Streams and event based trigger of Lambda

In my case the dynamodb stream view was enabled and set to New and old images. My Lambda function was filtering the events by eventName (set to INSERT). Suppose a new record has been inserted in the dynamodb and in that record one or more items changed their state/values from the previous record. Is it expected that the event will report both old and new snapshots? (context on dynamodb table - the Partition key is customer_id and sortkey is utc timestamp)
