Bioshock 2 Ending(s) Question...

[Major_A]

I just beat the game and only played as "good". I'm not going to replay the game the other way to see the ending. I installed RAD Tools to watch the endings and I have a question. What does the ambend in the filename represent?
Example the ending filenames:
gul_game_ambend_evil
gul_game_ambend_good
gul_game_end_evil
gul_game_end_good

I assume it has to do with the ratio of little sisters that you harvested throughout the game. If you only harvested one and saved the rest it would be gul_game_ambend_good? I didn't harvest anyone and I let all the jerks throughout the game live so that ending would be gul_game_end_good? I'm just a bit confused here because I just watched a few endings (the good ones) and I'm lost.

I just watched the different endings on youtube

Have you seen all 4?

I'm going to be evil for sure if that's the case.

I watched them all but I guess I'll have to hit up Youtube to be certain that I did in fact watch the right ones. The endings were split into several bik files and you can only open one file at a time with the RAD Tool kit. It doesn't help the Movies folder in Bioshock 2 contains close to 200 files either.
