Look, you are welcome to your 'opinion' but the q remains (given that there are only 2 choices here) as how pipeling is a form of "synchronous" communication.
[p.s.]:
pipelining is a kind of async comm because unlike the general case of asynchrony, the response order mirrors the request order (which is not a requirement of the general case.)
