Answer 1

It doesn't mean anything significant, you can ignore this parameter. It is just an artifact of a very old pocketsphinx API.

Originally in pocketsphinx the API allowed to set the ID for every utterance it starts recognizing, so that in pocketsphinx log the recognized results are attributed to a certain wav file. Now there is no much need in that and this parameter will be removed from pocketsphinx API most likely.
