Feel free to propose alternative wording with the same precise meaning.
Keep in mind that these terms were invented to convey a more
precisely-define meaning than existing terms would have provided, so
wording that says "approximately" the same thing would not be an
acceptable replacement.

I'm no expert in multi-threaded code, so I don't fully understand the
significance of what it says. However, I able to derive the fact that
there is a difference between the two terms only when one evaluation
"inter-thread happens before" another evaluation, and the two
evaluations are not synchronized. In other words, the difference is with
regard to what's required for unsynchronized threads.
