You're right, thing is I don't know if it's in far enough, it looks like quite a conservative amount of quill actually goes in even after I cut it down drastically. I've not ever seen a quill with that short an insert.
Will probably get the thread on the bolt extended anyway, this is where it sits in the bike now
If the mark above the circle on the section you've cut off is the minimum insert line then I'd say it looks like you currently have more than the minimum suggested insertion.
