Question about enabling Automatic Shared Memory Management

Platform is Oracle 10.  

I thought that ASMM was enabled by setting sga_target to a non-zero value.  

But I recently read the notes below, which confused me.  

Do I really need to set shared_pool_size to a non-zero value? I thought the whole point of ASMM was that oracle calculated shared_pool_size?    

Oracle Automatic Shared Memory Management is enabled by setting:

• You must use an spfile for the init.ora values
• sga_target parameter is set to a non-zero value
• statistics_level parameter set to to TYPICAL (the default) or ALL
• shared_pool_size must be set to a non-zero value
