No, this sentence applies, just as if there were no expansion
opportunities within the text:

   # If the inline contents of a line cannot be stretched to the
   # full width of the line box, then they must be aligned as
   # specified by the ‘text-align-last’ property.

I can clarify that point.

Because
   * { text-align: start !important; }
in the user style sheet would mean a rule like
   caption { text-align: center; }
would not take effect.

I've clarified the definition to say

none
   Justification is disabled: there are no expansion opportunities
   within the text.

Let me know if this is sufficiently clear.
