What you're describing is actually more like what Gay did. Oxman was caught copying from Wikipedia without any attribution. If you look at the supposed examples of Gay's plagiarism, she cites the works she's using. Most of the examples are of the form, "As John Smith writes, a dog can often be a man's best friend (Smith 1990)." Then you look at Smith (1990), and you find something like, "A dog is often a man's best friend." Gay's mistake was leaving out quotation marks when she paraphrased too closely. It's not really plagiarism in spirit, because she's obviously not passing off anyone else's work as her own, but it could run afoul of the rules.
