The only problem I see with doing it in two is you have a joint which isn’t reinforced with re-bar so could sink or settle in the future.
This is the problem , it may possibly crack on the joint in time .In the past when I’ve been faced with this I’ve drilled into the existing pad at 45 degree angles , hammered in re bar then bent it back at 45 degrees the opposite way and laid the new concrete . It gives the joint a little stability, ties the two parts together as such , or at least it does in my mind ! Put as many in as you can within reason .
I’m not saying it’s a perfect solution but I’ve never had a problem over the years , I did it a while ago when I extended my own patio area off an existing pad .

I did the same, just drilled metal rods in. It's how you'd tie an extension in to an existing house and absolutely fine for a patio. It probably is still the weakest point in theory but if it's strong enough it doesn't matter.In the past when I’ve been faced with this I’ve drilled into the existing pad at 45 degree angles , hammered in re bar then bent it back at 45 degrees the opposite way and laid the new concrete .
