It's even easier to explain than that. The RAM is integrated into the CPU. While there are a few SKUs here, Apple only designed and built one CPU with 16GB RAM. The CPUs are binned. The CPUs where all RAM passed testing are sold as 16GB, the 8GB SKUs had a failure on one bank of RAM.

There are no 32 or 64 GB models because Apple isn't making a CPU with 32 or 64GB of RAM yet.

It looked to me that they were placing 2 DDR4 modules beside the chip.

Well maybe? Huh. I don't know now, certainly looks like it.
