Yes. You got it.
Combing is a feature to speed up printing. It can make a big difference. But it can also lower quality. Normally combing moves do not retract (although there is a "max combing distance with no retract" feature to fix that). zhop only happens on retractions. So A implies B implies C therefore A implies C (combing means no zhop).
By the way, zhop is only recommended for delta printers and 99.9% of the printers out there are not delta printers so you might get ugly horizontal lines if you have zhop on. Or maybe not. Or maybe you will get them in a few months when your z screws get dirty.
yes the print head can slam (hard) into the edge (or infill) particularly on overhangs like the bow of benchy. But so what. If you have everything figured out correctly (like excellent bed adhesion) that won't be a problem.

I'm having the same problem. I suspect this had something to do with combing. My next print I'm turning that off. I'll let you know.
UPDATE: Turned off combing and that issue went away. I suspect there's a bug with combing. Either that or I just don't understand it correctly. It appears to me that if combing is turned on it skips z-hop all together.
