They have been producing the Mobil Super Synthetic 0W-16 for years now. It's a GTL-based oil, similar to the TGMO 0W-16, which is also GTL-based, and as opposed to the PAO-and-AN-based Mobil 1 AFE 0W-16, all three of which are made by different divisions of ExxonMobil (TGMO being made by the Exxon Mobil Industrial Lubricants).
It is not possible to make an SN PLUS/Resource Conserving 0W-16 oil because SAE 0W-16 is not an ILSAC GF-5 grade and Resource Conserving is part of ILSAC. What you see on the data sheet is a typo. SAE 0W-16 will be part of ILSAC GF-6B when it's introduced on May 1, 2020, along with API SP, not API SN. They can then have an API SP/Resource Conserving 0W-16.
An interesting thing I see on the data sheet is that the density for the Mobil Super Synthetic SAE viscosity grades are all over the place, which is suggesting that they use all kinds of base oils, such as high-quality GTL or low-quality Group III, depending on the SAE viscosity grade. Normally the density tends to increase from 0W-16 to 10W-30 if the same type of base oil is used, as thicker base oils are heavier, also needing to consider more VII content requires thinner oil for a given SAE cold viscosity range.
