2.13.3 API says:
def addOne(elem: A): ArrayBuffer.this.type
Adds a single element to this array buffer.
final def append(elem: A): ArrayBuffer.this.type
Appends the given elements to this buffer.
They seem to do the exact same thing?

They are the same thing. ArrayBuffer is a descendent of Buffer, which defines append:
@`inline` final def append(elem: A): this.type = addOne(elem)
addOne is implemented in ArrayBuffer as part of its implementation towards Growable.
See: Buffer.scala.
