Perhaps we need to look at the naming, I find it quite natural for people to expect something that is extended to be longer than the standard version!
To explain how the slightly odd situation has arisen I will point out the "extended" applies to the k value, as the extended k testing starts from a lower n value it is faster at present, as the years go by the difference will shrink and maybe disapear or reverse.
Nothing here on PG is ever as simple as it looks at first glance.
