All these generators are manufactured for the USA market, in which 110V is the single phase voltage supply, the 0-V connection, however phase to phase is 220V AC that would be the V-V connection.
It just so happens that the V-V matches our nominal 220V equipment.
The reason for this is that due to the low voltage of 110V AC for domestic and industrial supply and substantial load, will cause the current to be high, meaning wire sizes and circuit breakers have to be beefed up to match.
So high power loads, such as stoves, welding machines, power tools and heaters to name a few are connected phase to phase, and hence the generator was manufactured to accommodate the two different loads that may be required to run on the generator.
