--opencl-device-types vs. reported Device #?

OpenCL Platform #2: Intel(R) Corporation
========================================
- Device #2: Intel(R) Core(TM) i3 CPU         550  @ 3.20GHz, 4061/16247 MB allocatable, 4MCU


While running hashcat64.exe --opencl-device-types 2 gets:

OpenCL Platform #1: NVIDIA Corporation
======================================
- Device #1: GeForce GTX 970, 1024/4096 MB allocatable, 13MCU

OpenCL Platform #2: Intel(R) Corporation
========================================
- Device #2: Intel(R) Core(TM) i3 CPU         550  @ 3.20GHz, skipped


Is the device numbering opposite, or does the command option do the opposite?
