Sure but that doesn't change how long they supported after end of sale which wasn't in 2013 but at least until 2017. So ~3 years of software updates from end of sale. Still OK but not anything special.
Certainly not the Pixel phones, they get 3 years support from first launch only, and they're supposedly the gold standard for Android software support. It's pretty much the reason they exist. Yet after last sale support for the 5S matched the Pixel's from launch support, and we don't even know that this is the last update the 5S will get.
You can’t have your cake and eat it as well.
