They all work correctly. I have done input/output on those three SMs.

root@:~# ethercat pdos
SM0: PhysAddr 0x0f02, DefaultSize    0, ControlRegister 0x44, Enable 9
  RxPdo 0x1a00 "Byte 0"
    Pdo entry 0x3101:01,  8 bit, "Output"
SM1: PhysAddr 0x0f03, DefaultSize    0, ControlRegister 0x44, Enable 1
  RxPdo 0x1a01 "Byte 1"
    Pdo entry 0x3101:02,  8 bit, "Output"
SM2: PhysAddr 0x1000, DefaultSize    0, ControlRegister 0x00, Enable 1
  TxPdo 0x1600 "Byte 0"
    Pdo entry 0x3001:01,  8 bit, "Input"
  TxPdo 0x1601 "Byte 1"
    Pdo entry 0x3001:02,  8 bit, "Input"

Does it make any difference if I map only PDOs that belong to a SM at a
time?

It is configurable. This EL9820 data sheet will be helpful. See page 4.
