Looks like you typoed the unit of measure. Thats 2 cm, not mm, 10x bigger.

However, exceptions include sharp or toxic bodies, objects too large to pass through the pyloric sphincter (greater than 2×6 cm),

The pylorus contracts to slow gastric emptying and results in further mixing of gastric contents. During this time, the stomach transforms its contents into multiphase slurry called chyme, which is a combination of separate phases of aqueous solutions, fats, and solids. The more intense peristaltic waves promote antral empty- ing, which allows gastric contents, mainly fluid mixed with small particles, to pass through the pylorus and enter the duodenum. The particle size of the food emptied through the pylorus is less than 1 to 2 mm during the fed state (Thomas 2006).

  I don’t read any conflicts here, in fact it seems the blurb you shared is speaking to normal food particle size that passes though, while the one I shared talks about maximum foreign object size that can pass.
