Question about " The maximum number of operations per yield point is 500" ?

[YohanWadia]

Hi
Im trying to update more than 100 contacts at a time...
the only thing that I am updating may be 1 or 2 phone numbers in the entire contact.
between each consecutive contacts update I am using await.

My question is what is meant by "max number of operations per yield point is 500?

Does yield point mean that one contact that I am updating? and that should not have more than 500 properties?
But what if Im only updating 2 properties out of 10... does that still count as 10 operations?
... and if I am updating contacts with many properties... is it fine if I am calling await between each update?

Thanks,
Just wanted some clarity,
YO
