2002 s60 Is this the right way to set timing for VVT motor?

If the cvvt mechanism is working properly, once you get the timing belt off you should be able to rotate the hub back and forth. Some of them are spring loaded, on my S60 it was not. This is part of the reason you need to be able to see the back end of the cam- the gear and hub mechanism can appear to be in the perfect position, as far as the marks go, but the camshaft itself can turn. Its possible that the camshaft shifted a tooth while you were installing the timing belt, but because you used the gear marks to align everything you didn't notice.

I would remove the cam position sensor and the reluctor that is under it (10mm bolt to get that off), then put a wrench on the crankshaft, turn it clockwise at least twice, carefully line up the marks (without EVER turning it counterclockwise), and take a look at the slot. it should be parallel with the seam; if it isn't, then you know why the engine isn't running smoothly.

I think you can get the timing cover off without removing the serpentine, but it is a little bit harder to turn the engine with all the accessories hooked up.

Curious, I bought a 06 XC70 with 2.5t and the previous owner tried to fix oil leak from exhaust CVV (O) ring which was broken. So obviously he loosened the hub to remove. He said he did lock cams, hopefully. Anyway, he said first the car would start, but ran rough, then tried to better time it, and then would not start at all, so he gave up. So in checking, the timing was off quite a bit, couple tooth which would explain no start situation. My question is how much off before you bend valves? Is a couple teeth going to cause damage? I have not done compression check yet, but before buying one, thought I would ask if a couple teeth off is the kiss of death.

Ive read here it is of the order of 3 teeth before you hit the kiss of doom.
