I'd always add a new chest to an existing vendor, rather than edit the one(s) they have, or else as JDFan points out, any other mod that edits them could wipe out your changes.
IIRC the reason that some vendors are given multiple chests is that the developers made a "Alchemy vendor chest" and a "Food Vendor chest" and if a merchant sells both they just give them both chests instead of creating a third combo one just for them. Sometimes that's a "base level" container, plus a "Special stuff" one of the same type of goods, I.e all other vendors sell the the base items, but this is a vendor who has extra items for sale. If you're adding things to multiple vendors, you might want to use the same scheme of merchant containers for your items.
