No, you didn't do a first run. You simply generated "/mnt/rescue1.log". 
Option '-g' (which has been renamed to '-G' in ddrescue 1.18) is not 
meant to be used in normal rescue mode (see below).

Once again, you simply generated "/mnt/rescue2.log".

http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Generate-mode
"NOTE: When ddrescue is invoked with the '--generate-mode' option it 
operates in "generate mode", which is different from the default "rescue 
mode". That is, if you use the '--generate-mode' option, ddrescue does 
not rescue anything. It only tries to generate a logfile for later use."
