In fact --interlaced command here is useless. you must just know if your interlaced source is bff or tff.

Depending on the underlying implementation, TFF vs BFF might just be a matter of signalisation. TFF just means that within a frame made of 2 fields, the top field should be displayed first, and BFF that the bottom field should be displayed first.

Yes, dattrax's patch that adds those parameters is only about signaling interlacing properties within the SEI info. Parameter --interlaced is the MBAFF switch in vanilla x264 and the patch adds --tff and --bff.
