Rumors about Samsung working on slim devices have been going for longer, and they already did launch such a device on the market: the Galaxy Z Fold Special Edition was internally known as the Galaxy Fold 6 Slim.I’m sure this is just a total coincidence.
Samsung has always acted like little brother
So unless you're implying Apple is copying Samsung; yes, this is just a coincidence.
Lets completely disregard that neither companies can make up plans for such a device on a whim here...
