Should inline comment always end with the period?

Based on API documentation and comment standards

we can read that:

- All summaries (first lines of docblocks) must be under 80 characters, start with a capital letter, and end with a period (.).
- One-line summary, ending in a period (.).

plus the logic of Coder where it adds period on every inline comment, see:

- #2742881: Can inline comments end with semicolons
- #2607574: Don't add dot with inline comments containing code with semicolon

Following above logic, does it mean the page about coding standards doesn't following these standards?

Example 1:

  // @todo Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam
  //   nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat,
  //   sed diam voluptua.

Example 2:

  // Sample code here

Example 3:

// Note: especially in Drupal 8, these callback implementations may be
// class methods rather than functions, which are passed in as PHP
// callables rather than strings. So an alternate wording that
// implies that this is also acceptable would be:

If so, should these examples be fixed? And documentation clarified when we should use periods at the end of the lines for inline comments?
