Laying flagstone in newly poured walkway

Good morning, I have a question about laying flagstone. I used your site extensively to lay a flagstone patio over the summer, it turned out very nice and thank you for all of the information! I layed the stone on a concrete pad that I had poured last year and used your mortar mix to lay the stone.

My question is this, although it is getting late in the year and temperatures are in the 40's-50's here in northeast ohio, I am having a friend who owns a concrete company pour a new walkway (a previously dirt path.) My father wants to lay the stone in the pathway while it is still wet. I rather wait till the spring and lay the flagstone the way the patio is done but he seems to think his way is the right way. Any thought and opinion would be great.

Thank you,
Brian
