X more than Y, is the correct idioms. X and Y need to be parallel to each other. If we use "summarizing", the sentence will be "Does" vs "Summarizing", this relationship is not parallel, since Summarizing is not a verb in this context.
"Does" vs " summarize" is parallel; Hence, the sentence is correct!
