Obligatory "Well Actually": the poem isn't trying to demonstrate the technology behind spellcheckers (or correctors). It's demonstrating a near-universal weakness of algorithmic checking/correcting that isn't shared with human proofreaders: when the mistaken word is the correct spelling of another word. The poem takes this to absurd extremes, but it's quite possible to make such mistakes through typos (e.g., "pun" instead of "pin").
