I just answered this question but perhaps it was in another thread :oops:

Remember though just because your snake assumes an S position it isn't always related to feeding or indicating your snake is hungry at all. They are incredibly protective of their heads and will often keep their head well back while they stay still and assess a situation. Once they feel safe, they will continue to move about but sudden movements often result in the quick drawing back of their head. Doesn't even mean they are preparing to strike, it's just that instinctive need to keep their vulnerable head protected.

Once you get to really know your particular snake, you can more easily read body postures, level of tenseness of their muscles, the hisses they make, even if a strike is really meant to connect. What might indicate an impending serious bite attempt in one snake, might read completely differently in another. Until you get to know your snake extremely well though, it's just smart to go with general guidelines of handling, feeding, etc.
