Even though Snape knew about the plan, he still would want to use 
Legilimency on Narcissa, to find out more about her motives. What if 
it was LV who sent her to ask for help in order to put his loyalty to 
the test? Or what if Bellatrix was just pretending she disapproved of 
Narcissa's behavior, and she was actually behind it, hoping to 
discredit Snape in LV's eyes? It was better to Legilimence her just 
in case :-). 

Once Snape looked into Narcissa's eyes, he realized she came of her 
own accord, and he decided it was safe to take the vow, because LV 
knew nothing about it, and Bella wouldn't want to incriminate her own 
sister (and herself) by telling him.
