AWS Blog Posts – Different Authors – Same Content?

While searching for data streams on AWS I came across two articles set a year apart - which have more or less the same content with a few words shifted around.

https://aws.amazon.com/blogs/database/streaming-changes-in-a-database-with-amazon-kinesis/

https://aws.amazon.com/blogs/database/stream-changes-from-amazon-rds-for-postgresql-using-amazon-kinesis-data-streams-and-aws-lambda/

I am wondering whether this was done intentionally (as in SEO) or ......?
