Understanding of SQL Server documentation

Question

This SQL Server documentation page states that:

SQL Server ignores NUMA configuration when hardware NUMA has four or less CPUs and at least one node has only one CPU.

1. This sentence seems indicate that different physical NUMA node could have different number of physical CPUs. Is this true?
2. I don't quite understand the logic here (maybe because I'm not a native English speaker). Does the following pseudo code represent the logic in the excerpt? fn is_sql_server_ignores_numa () {
   one_node_has_one_cpu = false
   for node in all_numa_nodes:
   if node.cpu_count() == 1:
   one_node_has_one_cpu = true

      less_then_or_equal_to_4 = true  
      for node in all_numa_nodes:  
          if node.cpu_count() > 4:  
      less_then_or_equal_to_4 = false  
   
      return one_node_has_one_cpu && less_then_or_equal_to_4  
   

   }
