I would imagine that a gentleman going by the name of "Retro Grouch" is probably familiar with a Silca type pump head.
Regarding ease of inflation...I think that was his point, if one has a hose that is connected to an on demand compressor, like at a gas station, Schrader heads/valves are quicker, potentially, as they provide instant inflation just by making proper contact, whereas the Silca type as pictured would require an additional mechanism to prevent the air from escaping when not inflating the tube. ( Think NASCAR pit stop for reference.
