There was no point in the FLAC version. The version available is literally the same exact music just not blown up to a huge degree for no reason.
Zeratul13 already explained why there was a point. But let me clarify it for you through a simple analogy:
Let's take the audio spectrum image from an earlier post
and compress it to JPEG (lossy):
Note how the fine details of the spectrum are blurred due to compression. (You may need to download both images and cycle between them to see the difference)
Now let's open this JPEG file in any image editor and change something in the picture.
I just drew a couple of red circles using MS Paint. Then I saved the file in PNG (lossless compression) and uploaded here:
But before closing Paint, I also saved the edited image in JPEG. Here is the result:
You may notice that the quality has deteriorated further (especially in circled areas, but in other parts as well).
The new PNG file is 185 KB in size, but apart from the edits it looks identical to the 2nd image.
The new JPEG file is only 34 KB in size, but looks a bit worse.
Both files were obtained after editing a lossy source.
Exactly the same happens with audio, where JPEG is mp3 and PNG is FLAC.
When you edit an mp3 source and save the result back in mp3, you can't avoid recompression and further loss of quality.
When you save the result in FLAC, you keep all losses which were in the source but avoid further degradation. Files are bigger, but well.. beggars choosers
After reading this thread I felt somebody had to support the OP. Hope this helps.
