Like you, I'm just going by what it says, but was not confused they specifically say basically this is some kind of new product, in alpha version, maybe only an advancement in the way the product is incorporated into the machines idk.
"...The Developer's Kit allows an OEM to seamlessly and quickly embed PrintRite3D(R) technology directly into their products..."
So my thought is that previously this was not possible, maybe without huge modifications, etc idk.
Good questions...
