Placement of the comma depends on the sense and flow of the sentence.
"Janey likes tomatoes but does not like apples" does not require a comma at all because it is a relatively short thought with only one subject (Janey) and, therefore, is unlikely to confuse anyone.
"Janey likes tomatoes and does not like apples, but her brother likes both." This sentence consists of two phrases, one with Janey as the subject, the other featuring her brother. Here a comma before the change of direction (from Janey's preferences to her brother's preferences) makes the sentence read more smoothly.
"Janey likes tomatoes but, according to her brother, does not like apples." This is essentially the same as the first example but with a brief qualifying phrase that reads better when isolated from the main thought.
