I believe BC simply listed it improperly; on REI, they are a bit more concise about what the pot specifications are. For instance, they list the liquid capacity as being 1.4 L ( or 48 fluid ounces), but the dimensions they list as the same. However, one thing that they clarify on REI is that what this set comes with is a 2-liter pot, titanium lid, and a plastic sealing lid. Basically, I think technically it is a 2-liter pot, but it's only meant to hold up to 1.4 L of food/liquid at a given time. If you check out this link (http://www.rei.com/product/831568/snow-peak-titanium-cook-n-save-pot#specsTab), scroll over the picture they provide and it will auto-magnify; whilst doing that, observe the measurement indicators pressed into the metal sidewall of the pot; you will notice that the measurements end well below the rim of the pot, which is why both specs are technically right, but to definitively answer, the pot is only meant to cook up to 1.4 L of anything at a given time.
Hope that helps!
