In James Baldwin's essay Everybody's Protest Novel, there is the following sentence:
It must be remembered that the oppressed and the oppressor are bound together within the same society; they accept the same criteria, they share the same beliefs, they both alike depend on the same reality.
I know that repeating the word or phrase at the beginning of a clause is called anaphora. In this case, that word is "they." Also, I know that repeating the last word or phrase in a clause is called epistrophe. Now, is there a name for repeating a word or phrase in the middle of a clause as is the case with "the same" in the sentence above.
Related to the same sentence, the short independent clauses after the semicolon are separated by commas and there is not coordinating conjunction. Is this common grammatical practice or not?
EDIT: The second part of the question has already been answered here.
