Sure, but they were parallel requests in the first place, so in terms of wall time you're still only taking the latency hit once. And if they're larger in aggregate than the connection's BDP some of them would only have finished by the time that it has recovered from the loss anyway.
So... it's complicated. I'm not saying that HoL is a non-issue and that TCP is perfect. It's just that you're not eating the latency penalty N times and for anything that is dominated by throughput rather than latency it's even less relevant.
