[Bug-ddrescue] ddrescue results: are these ok?

I have a broken 500GB disk rescued to a brand new disk with ddrescue.
In the first run I saved as much as possible with --no-split. The second I
tried to squeeze out as much as possible with --direct --max-retries=3 

In this second run I get some remarkable shell output. The previous last
result table looks like this

rescued 500107 MB
ipos            772441 kB
opos            772441 kB
errsize 562 kB
errors          124


and the latest table:

rescued 500107 MB
ipos            278263 MBkB
opos            278263 MB
errsize 0 B
errors          0


I don't understand why the error count has disappeared suddenly in the last
table, while the value for 'rescued' stayed the same all the time. Also the
ipos and opos values rocketed into air. What do these values mean, and is
this suspicious?

Also I would like to hear if I should clone my new disk to an even newer one
in case efsck will destroy my recovery result. Or is this unlikely when
ddrescue reports zero errors?
