When cooking pancakes and similar recipes it's important to avoid dripping batter onto the sides of the frying pan, or - if some should drip - to wipe it away immediately with a piece of kitchen paper. This is because small, thin quantities of batter will burn quickly and would affect the food you are cooking. The same applies to drips of egg on the pan when cooking omelets.
You might be referring to recipe instructions which ask you to ensure the batter is kept in the middle of the base of the pan while cooking. This, again, is because thin areas of batter on the outside will cook too fast compared with the centre.

The bicarb in pan cake batter releases CO2 gas while the pan cake cooks , making it light and airy. If you let the batter sit, some of the CO2 may be leased before you cook it and your pan cakes may be heavier. Besides the CO2 ,you introduce air in the batter when you beat or stir it and this too helps make the pan cakes lighter and will leave the batter if it sits.
