The CIB is one element in a chain of 0 to a maximum count, depending on how you initialized processing. I usually set the maximum to 1 because that makes the logic a little simpler.
When your program starts, there may or may not be a START CIB. You should see one in an STC, but not usually when running under an initiator.
After you set the maximum CIB count to non-zero, the CommECB is posted when a STOP or MODify adds a CIB to the chain. After you process that CIB, you would normally free it.
Once you understand the processing, the QEDIT description should make more sense.
Also note that a STOP command posts the ECB with an X'50', whereas all others post with X'40'.
