Nope.

In the US the transformer for most residential power taps one of the 3
phases in the power distribution system, which is why it is called
single phase, even though there are 2 hot legs.

The transformer center tap on the pole is grounded and also connected to
a wire called neutral. This provides two output voltages relative to
ground or neutral. Each is 120 V, but they are 180 degrees out of phase
with respect to each other.

Your understanding of electrical things is not very good. I have many
years as an electronic tech. I have tested with an oscilloscope your
theory and proved it wrong. The two legs of a 240V are in phase.

But in the end it really does not matter because everthing electrical
will still work as long as it ain't broke.

Then you should know the difference between electric and electronic.

I do, do you?

You just think you do ... read the second sentence and weep:

The two halves of the transformer are 180 degrees apart, not the
signal. Question what do you get when you add 120 and -120?

The question is not what you get when you add 120 and -120, the
question is the (potential) DIFFERENCE. Answer; 240V.
