This version is more than one year old, you should consider compiling
current svn version, or get a newer version.

I think it skipped some parts, even if it is not as precise as you want.

Actually, using edl while copying streams can not be precise, because of
the video encoding nature (Immediate and Predicted frames).

To get an accurate skip, you have to use -hr-edl-seek, and to reencode
the streams.
