Maybe the 2020 NEC enhanced interpretation will help
(1) Receptacle Outlets Served.
In the kitchen, pantry, breakfast room, dining room, or similar area of a dwelling unit, the two or more 20-ampere small-appliance branch circuits required by
210.11(C)(1) shall serve all wall and floor receptacle outlets covered by
210.52(A), all countertop outlets covered by
210.52(C), and receptacle outlets for refrigeration equipment.
Exception No. 1:
In addition to the required receptacles specified by
210.52, switched receptacles supplied from a general-purpose 15- or 20-ampere branch circuit as required in
210.70(A)(1), Exception No. 1, shall be permitted.
Exception No. 2:
In addition to the required receptacles specified by
210.52, a receptacle outlet to serve a specific appliance shall be permitted to be supplied from an individual branch circuit rated 15 amperes or greater.

The limited exceptions to
210.52(B)(2) keep loads for specific equipment to a minimum so that the majority of the circuit capacity is dedicated to supplying cord-and-plug-connected portable appliance loads. The
NEC restricts the loads supplied by these receptacle circuits because the number of cord-and-plug-connected portable appliances used by occupants is generally undetermined. Receptacles and other types of outlets in other locations, such as in cabinets, are not permitted to be connected to the small-appliance branch circuit. Such outlets reduce the capacity to supply portable appliances used at a kitchen counter.
No restriction is placed on the number of outlets connected to a general-lighting or small-appliance branch circuit. The minimum number of receptacle outlets in a room is determined by
210.52(A) based on the room perimeter and on
210.52(C) for counter spaces. Installing more than the required minimum number of receptacle outlets can also help reduce the need for extension cords and cords lying across counters.
The exhibit below illustrates the application of the requirements of
210.52(B)(1),
(B)(2), and
(B)(3). Only the counter area is required to be supplied by both small-appliance branch circuits. The wall receptacle outlets in the kitchen and dining room are permitted to be supplied by one or both of the circuits as shown in the two diagrams.
Exception No. 1
Switched receptacles supplied from general-purpose 15-ampere branch circuits may be located in kitchens, pantries, breakfast rooms, and similar areas. See
210.70(A) and the exhibit above for details.
Exception No. 2
This exception provides a choice for installing receptacle outlets to supply refrigeration equipment or other specific appliances in a kitchen or similar area. An individual 15-ampere or larger branch circuit can serve this equipment, or it can be included in the 20-ampere small-appliance branch circuit. A receptacle supplying refrigeration equipment is exempt from the GFCI requirements of
210.8 where the receptacle is greater than 6 feet from the edge of any sink and where it is located so that it cannot be used to serve countertop surfaces, as shown in the exhibit above.
