You only *appear* to have two phases when you hook one pair of your
oscilloscope leads up backwards.

On the secondary side of the transformer, you have 2 voltage sources
(both the same voltage). If the phase is the same also, you could
connect both together, for more current.


That's true and it also demonstrates that when you treat the transformer
as what it is, two voltage sources differing in phase, it's all
covered. With phase difference of zero, you would have two voltage
sources in perfect sync that could deliver current from both,
like you just said.
With phase difference of 180, you have two sources that deliver
120V with respect to the neutral, or 240V between the two sources.
With phase difference of 90, you have Ralph's two phase from 100 years
ago.
