REORGANIZE seems to work as well as REBUILD all the time
Let me quote another part of that same page, which basically says IT DEPENDS - emphasis mine:


  These values provide a rough guideline for determining the point at which you should switch between ALTER INDEX REORGANIZE and ALTER INDEX REBUILD. However, the actual values may vary from case to case. It is important that you experiment to determine the best threshold for your environment. 


There's not really a good answer for this except "it depends"... those are just general guidelines and may or may not be appropriate depending on the number of rows, the columns in your index, their data types, how wide the index is, what else is getting written to disk in between writes to those tables, etc. 

Like how big should I size tempdb, what is a good threshold for PLE, and what type of car should I buy, the answer is the same: IT DEPENDS.
