According to the System Management guide the Load Module Auditor exit, PVLMAUD, will insert a CSECT and DC statement immediately before the END statement when assembling assembler programs if PVLMAUD is implemented and the ' END ' statement starts in column 9.
What the manual is trying to convey is the leading blank in ' END ' must begin in column 9. The E of the END statement must begin in column 10.
The END statement requirement in the System Management guide in Chapter 9: Generalized Exits, Load Module Auditor, Specifications For the Sample Exit specifies:
Note the leading and trailing blanks around END, so ' END ' is read as "blank,END,blank"
The leading blank starts in column 9, END is in 10-12, and the trailing blank is in 13.
