That is true as long as the wire is sized appropriately for the breaker. For instance, you should never wire 14/2 with ground to a 20A breaker.
I don't believe that is true. Both outlets from the duplex are wired in parallel. If either outlet or both combined exceed a 20A draw, the breaker will trip. You can't draw 20A from each outlet. There is only 20A available for both outlets combined.

I tend to agree with you
By code here a 20 amp line must be wired with 12G and a 30 amp by code must have 10G
My 30 amp AC outlet was not duplex but rather a single outlet per receptacle and I used appropriate wiring for each.
