Is villain hoping you'd pat back a 9 on the 3rd draw that you'd otherwise break had villain 4bet turn? Like if you have 97432, you'd prob break and draw to the nuts vs a 4bet/pat but maybe you'd pat back after he just calls the 3bet hoping your opponent has a worse 9. Or perhaps with a rough but still nutted redraw with a stronger 9, like 96432 or 95432, the 76 not 4betting gets you to pat back incorrectly.
Villain is legitimately scared - his check/raise is a strong line so a 3-bet should be quite strong here. I don't know if he should've capped or not, but his calling down doesn't seem that bad.
