That's only for the service calculation.
Yes, but it applies to minimum amount of circuits needed also.
Here is an example from the annex.
Example D1(a) One-Family Dwelling
The dwelling has a floor area of 1500 ft2, exclusive of an unfinished cellar not
adaptable for future use, unfinished attic, and open porches. Appliances are a
12-kW range and a 5.5-kW, 240-V dryer. Assume range and dryer kW ratings
equivalent to kVA ratings in accordance with 220.54 and 220.55.
Calculated Load [see 220.40]
General Lighting Load 1500 ft2 at 3 VA/ft2 = 4500 VA
Minimum Number of Branch Circuits Required [see 210.11(A)]
General Lighting Load: 4500 VA ? 120 V = 38 A
This requires three 15-A, 2-wire or two 20-A, 2-wire circuits.
Small-Appliance Load: Two 2-wire, 20-A circuits [see 210.11(C)(1)]
Laundry Load: One 2-wire, 20-A circuit [see 210.11(C)(2)]
Bathroom Branch Circuit: One 2-wire, 20-A circuit (no additional load
calculation is required for this circuit) [see 210.11(C)(3)]
