I don’t think I’m understanding the difference.

At the risk of distracting you with minutiae, this particular example feels more like a property access than a method call, so my mind wants to rewrite it as this:

someFont.glyphs[“LATIN SMALL LETTER A WITH ACUTE”]

and that makes it a little harder to stay focused on the intent of the guideline.
