Confused with Supermicro X11SPI-TF spec sheet

I'm looking at the specs for Supermicro X11SPI-TF and I'm a little confused at what seems to be a contradiction.
Key feature #3 specifies that it's capable of taking up to 2 TB of RAM.
However, if you scroll down further to "System Memory" -> "DIMM Sizes" section, max listed there is only 128 GB LRDIMM.
Obviously, that only works out to 1 TB in 8 slots. Am I missing something from the specs? Is there an appendix somewhere that lists max RAM of 256 GB LRDIMM or is this just a typo or oversight?

In the manual, it's 1TB max:

Up to 256GB of RDIMM, 512GB of LRDIMM, and 1TB of 3DS LRDIMM DDR4 (288-pin) ECC memory with speeds of up
to 2933MHz in eight memory slots

What a mess, lol. Manual sounds like the correct one, but I still want to know how they got 2 TB.
