Two logs files for a single database
Logs are written to sequentially, so only one would ever be used at a time.  So, no, there is no benefit from having two on the same database.

EDIT: I looked over the part about different drives.  I suppose there could be a need in having two log files if you are working with limited drive space and your original log file would outgrow it's drive and you cannot move it to a larger drive for whatever reason.
