Storage zones and exposure during opening can differ, so door contents may not behave exactly like items on an internal shelf. Follow the food's storage label and the model's guidance for each compartment.
What the observation tells you
The door is opened into the room repeatedly and its pockets hold differently sized containers. Comparing a recently added bottle there with an older container at the rear is not a controlled temperature check. It also does not show that an entire category of food is suitable for any door pocket. Some models provide specific arrangements for particular foods or accessories.
A useful next step
Keep sensitive chilled items in an appropriate recommended location, use a suitable thermometer and compare like conditions. If one area persistently fails to remain suitable despite normal loading, describe that pattern. Do not make unsafe food decisions from the fact that another shelf feels cold to the hand.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
