It does in this case. If you care about validating and broadcasting your own blocks as fast as possible you don't want to run the node in a cheapo VPS that is timesharing the physical CPU with a thousand other virtual machines.

But besides this irrelevant non sequitur my point still stands: nothing stops any serious miner from having his own "pool-grade" low latency & well connected node. It's orders of magnitude easier and cheaper than running a big mining farm.
