That would apply but it's somewhat odd to see the tone of surprise for something which has been widely mentioned as an optimization-turned-antipattern for SPDY or HTTP/2 since at least 2012 or so. I believe at least Chrome has also optimized so addresses which share the same IP (or SSL cert?) will be collapsed into the same existing connection rather than opening new ones.

Opening all of those connections is also something of an anti-pattern even for HTTPS depending on how much data you're exchanging relative to the SSL handshake cost – see e.g.:

The tone of surprise (in the paper as well as this thread) might have something to do with how the whole HTTP/2 stack has been sold as an unmitigated "good" for all and sundry. The paper also mentions how the SPDY whitepaper http://www.chromium.org/spdy/spdy-whitepaper presents exactly the opposite results in presence of packet-loss. The language in the paper falls short of an outright accusation but there's an implication that the promises of the new protocols have been oversold by the backers (mostly Google).
