single word requests - Did he really write 'punctive'?

A highly respected person, with a very exemplary reputation, has just commented on EL : Comment 'a more stative, habitual sense as well as the more active or punctive one.'

I had never seen the word 'punctive' so I looked it up; or I tried to look it up. Google forces me to accept 'punitive'. The Oxford Dictionary of English doesn't list it.

If it is not a word, then it should be; I like the sound of it. But if it exists and is not just a typo for 'punitive' then how is punctive different from punctual ?
