I'm not sure it should be considered as a reason for anything. The most important point of the article, imo, is:

  If a function is only called from a single place, consider inlining it.

You should consider inlining your function, not always do it. Recently, I made a mod for a game and I had to draw an UI by code, and there, it made sens to use one-time function because it made the code easier to read (super-expressive functions like DrawLeftPane() or DrawHeader(), and next to no ties between functions).

Most of the time, code readability should be prioritized over performance.
