First, forget about the backgroundBehavior property. It has nothing to do with the use of the terms "background" and "group"
Instead, the distinction is this: "background" and "group" refer to the exact same thing -- a set of controls (possibly other groups as well) that have been grouped -- but in different contexts.
"group" refers to it in relation to a card. A group is always referenced in relation to the card it is on. Group 1 of this card is perfectly fine, background 1 of this card is not and will generate an error: Chunk: bad chunk order (must be small to large)
"background" refers to it in relation to a stack. A background is always referenced in relation to the stack that contains it. You can reference a group in relation to a stack, but you are really referencing it in relation to the current card of the stack. For example, if the group/background in question isn't on the current card, the reference will fail. This is why you need to use
place background "whatever" onto this card
rather than
place group "whatever" onto this cd
Finally, because I haven't been confusing enough, note that backgrounds are referenced relative to the order they are created, groups in their layering order on the card. If you have two group/backgrounds in a stack: "a" and "b" and you created "a" first, then if you create a new card and place "b" onto the card and then place "a" onto the card, the name of background 1 will be group "a" and the name of group 1 will be group "b"
Just realized I haven't answered the actual question. The number of backgrounds on both cards is 2 because it's relative to the stack: the number of backgrounds is _always_ the same across all the cards of a stack. It's 2 rather than 3 because groups that are nested in other groups don't count as backgrounds. The number of groups on card 1 is 3 because all three groups are on that card. The number of groups on card 2 is 1 because there is only one group -- c -- placed on it.
Hope this helps.

I have a stack with two cards. Card one has three groups a, b and c. Group a is nested in group b. Group c has background behavior. Card two has c placed on it.
Results from number of:
Card 1 Card 2
groups 3 1
backgrounds 2 2
