Usually the potassium issue with B12 has to do with increasing red cell production. People so low in B12 who are also anemic may have this low potassium until the anemia is corrected.
There is alot of potassium in the red cells so they will rob the
plasma of potassium while being increased.
People with frequent loose stools or diarrhea will also lose potassium. And people on low calorie diets can become low too.
Some forms of renal tubular acidosis lose potassium in the urine.
