I guess Wonder Woman wasn’t much of a draw back in the early 1970s because her guest appearance is a surprise (there’s no mention on the cover) and she’s practically in the issue more than Superman.
Following up on Superman’s epiphany from the previous issue (he’d prefer to live a normal life), Wonder Woman’s Indian sidekick convinces him otherwise. It’s only a couple pages, but it’s effective, maybe because O’Neil’s dialogue for Superman is so desperate.
But then there’s the subsequent problem (where Wonder Woman takes over). Superman has super-brain damage and is acting like a (well-intentioned) goofball. It’s almost like they have him do Silver Age things, then deal with the “real world” consequences.
The sand double gets a solid explanation here, along with a goofy name: Pseudo-Superman.
The reprint back-ups are cute, but out of place for the serious–if humorously handled–feature story.
