When Harry 'dies' from Voldemort casting Avada Kedavra in the forest, why does he make Narcissa check if Harry is still alive?

I am not asking why Narcissa was chosen, only why anyone was chosen at all.

Before then, there is only one recorded moment when the aptly named "Killing Curse" did not do its job, and that happened to Harry.

Voldemort knows this happened because of Lily's protection of love, but there is no one there who loves Harry who would protect him and apply the love protection again.

I suspect that the reason why Voldemort checks is because he's worried that history may repeat itself (as it does), but is there any explanation that that was his reasoning?

Additionaly (and I don't know if this has been asked/if I should ask this in a seperate question) why was Narcissa chosen and not someone else?
