Why would he mention "measurable" before "results?"

Good question! Here, he's describing the kind of "results" that are good to include. By "measurable," he means results that are able to be measured, assessable, or computable. If the results are measurable, then you can see what has been done, what needs to be done, how much of it has been done, and so on. For example, it's better, say, that you conducted "X" amount of surveys and what they achieved rather than just saying, "I did surveys." Ex: Started marketing with customer reviews and increased sales by 15 percent. Ex: Interviewed and did onboarding for 10 applicants.
