    • In one aspect, an example method includes (i) receiving, by a computing system, from a content-presentation device a request for supplemental content for a content-replacement operation, with the request including an identifier of a stored replacement advertisement segment; (ii) selecting, by the computing system, a replacement advertisement segment for output by the content-presentation device in place of a modifiable advertisement segment; (iii) determining, by the computing system, that the selected replacement advertisement segment is different from the stored replacement advertisement segment; (iv) determining, by the computing system, whether the stored replacement advertisement segment is a valid replacement for the content-replacement operation; (v) determining, by the computing system, that the content-presentation device should output the selected replacement advertisement segment instead of outputting the stored replacement advertisement segment; and (vi) causing, by the computing system, the selected replacement advertisement segment to be transmitted to the content-presentation device.
