2133Mhz LPDDR3 in New MacBook Pro?

So I placed my order day 1 for the new MacBook Pro & did the 2.9Ghz i5 + 16GB of 2133Mhz RAM......BUT as far as I'm seeing, none of the Skylake CPU's being used in the new MacBook Pro support LPDDR3-2133Mhz?

As shown in the above link, these CPU's only support 2133Mhz speeds when using DDR4 RAM. When using LPDDR3 they max out at 1866Mhz....so what is the point of advertising 2133Mhz LPDDR3, if the CPU does not support it??

Maybe someone else can point out where I'm wrong her, but it seems pretty plain...CPU supports 1866Mhz, but Apple is putting 2133Mhz in the machine.....no clue how this makes any sense?
