'Shoulder kiss' is a bit shorter than 'press his mouth against their shoulder', so I was mostly just using it as a shortcut. Though, true, there are implications from the word 'kiss'. It is pretty much exactly the same move with both Sara and Daniel, though (he also does the 'amazed face cupping' with both of them, though with Sara, it's before the hug and with Daniel, it's after).

And obviously I need to watch Heroes 2 so that I can compare.
