Well you were referring to design...
"The real reason why you see an S4 the way it is now before your eyes is because samsung could not copy apple any further. Unless apple is planning on a huge redesign on their next gen iPhone (6), it seems samsung has copied all it can copy up until iphone 4(s)/5 models. They have utterly finished photocopying and analyzing apple's designs, it's dried up all of their "innovations"."
So its more like after getting sued for previous copies, Samsung started creating its own designs. GS3 came out in 2011 so they were at least working on the design in 2010.
Samsung hasn't been copying Apple's design since (Galaxy S3/4, Galaxy Note 2, Galaxy Note 8).
