so if the old sod is just tilled, won't that grow through the new seems also?
What type of sod?
This does happen down here by some folks. Not everyone down here does this but I have noticed most of the hispanics do it this way. Yes it plays havoc with the sprinklers if the heads are not tall enough but it does not appear to be a issue with most of the jobs I have seen. And actually the raised turf next to the curb lines appear attractive to me with the type of edging we do down here, makes it look more like little carpet pads.
However in general yes it is better to go through and till and add soil or other admin to the top soil before laying.
I have seen it done here in Colorado, with limited success, and in Washington State (upper Pac. NW) with decent results. I would never do it myself, I hate doing the job over out of my own pocket. I have done small repairs with the scape it of method and been fine. If it is really dead rake it well, or even do a dethatch on it. Rake well, add compost, walk away with a happy customer & money in your pocket
Have done this before - scalp old off, core plug then rake in a sandy fill and fertilizer. Then lay new sod over old. Works well with bermuda types, keep an eye out for interlopers resprouting through old, especially nut sedge if you do not have a history of working on this location. Have done it with fescue and rye/fescue mixes, still did well but had more weed control to do in the summer from existing bermuda growing through.
dead turf decomposing generates a lot of heat so it will heat up and injure the new sod roots.
I have used a power rake (dethatcher) to run over the dirt after we have cut it out with the sod cutter. It loosens the soil up nice without complete tilling it up.
All of these points are valid, to one degree or another. The professional LCO needs to be able, to look at a given situation, then, make the right call, for each individual circumstance.
Working with living plants, means not every situation is the same. Not every eco-system requires the same treatment.
