So if I am understanding this correct, a 125/250 cord rated at 50 amps can supply 50 amps on each leg of the 125 (100 amps total?).

Sort of. To get 50amps on each leg of 120VAC, you need to be sure that each leg is on split phase and has 240VAC between them. If this is not the case, and the two hot wires are on the same hot leg (meaning, you measure 0volts between the two hots), you will overload the neutral wire.

The are two hots and one neutraul wiring in the 120/240 cord. The neutral only carries the difference in load between the two hots--specifically, if you are using 20 amps L1 and 20 amps on L2, the neutral will carry 0 amps. 10 on L1, 20 on L2, the neutral will carry 10.
