Opening page has a tab/sample for "Async & Parallelism" - does perl6 / that sample illustrate parallelism or concurrency?

https://perl6.org/

This sample:

start { sleep 1.5; print "hi" }
await Supply.from-list(<A B C D E F>).throttle: 2, {
    sleep 0.5;
    .print
}

# OUTPUT: ABCDhiEF

A cursory glance looks like that is concurrency (running multiple idling things in tandem vs sequentially). This is not parallelism, which would require multi-threading and running across multiple cores (active processing/computing) at the same time.

Should this tab title be changed to "Async & Concurrency" ?

I'm not sure what the example illustrates but "multi-threading and running across multiple cores at the same time" definitely exists in Raku 🤔
