ASCII-8BIT, yes.

Yes.

The role for the primary encoding is the default for file I/O, nothing
more.  It does (should) not affect the source encoding at all.

|  it sets the source encoding, overriding the primary encoding.

Basically yes.  it overriding the default source encoding (ASCII-8BIT).

|5) Once the script has been parsed (but before it is executed) the 
|source encoding is used to set the primary encoding if the primary 
|encoding was not explicitly specified with -K, -E, or --encoding.

This step is not required as far as I understand.
