Well it means that he folded a few times to your openshoves, hence the lower overall VPIP. What you can see from his 17-30 and 12-18 stats is that he flats your minraises pretty wide, meaning you shouldn't go 100% minraise maniac mode just because he has close to 50% overall VPIP.
In summary he's not tight OOP no
(well vs normal raises that is)
