Sync, as the name implies, synchronises both ways.
Therefore, if one data base is changed, say on the phone, the corresponding database, on-line, is also changed... and visa versa.
So, if a contact is deleted on the phone, the same contact is deleted on-line during the next synchronisation. Ergo, if a contact is added on the phone, then the same contact is added to the on-line database.
For instance, if you were to delete all your contacts, for whatever reason, from your phone, then all your contacts would be deleted on-line during the next sync, and visa versa.
This is, "The Complete Guide to Fixing Goole Contacts":-
The Complete Guide to Fixing Google Contacts
which may help clarify any points.
If you accidentally delete some of your on-line contacts they can be restored thus:-

I always keep a backup of my contacts on the phone using...
Contacts > Menu > Import/Export > Export to SD card
that way I can restore contacts in an emergency.
Hope this helps.

Doesn't look as though you have read my second link regarding the restore of deleted contacts on-line.

I'm sorry, I do not understand the question.
if i add a contact, it's a regular contact
i have the option to merge with google
yes i read ur 2nd link apparently it's not based on s2 so restoring contact option does not exist

With all due respect, I suggest you re-read it, my second link has nothing to do with the phone whatsoever.
It is a guide on how to restore deleted contacts on Google on-line.
if i set up contacts again, sync it.
then reset my phone, my last change should be adding not deleting right?
since a reset cleans the phone memory
Both - that's the point of syncronisation. Unless you mean changing the same contact on both, in which case the most recent change will take precedence.
so let's say i first delete a contact on my phone, then i go on google account to edit taht contact, then i press sync. the contact would still be on my phone after?

OK... lets think about this.
Each creation, alteration or deletion is given a time stamp so that the operations can be carried out in order.
So, let us say, that you delete a contact at midnight on your phone which has sync off.
You then go on-line to Google contacts on your PC and alter the same contact at 5 past midnight.
You then open up sync between the two and all creations, alterations and deletions are done in order.
So the contact in Google on-line would be deleted, and cease to exist, prior to your later instruction for the amendment to take place and so since the contact would no longer exist in either data base... the amendment would be cancelled out.
I trust that this answers your query.
i thought the sync would be as a whole contact list, not just by each contact. so if a contact was deleted earlier, it will sync with 1 less contact. then another change was made, with the original contact edited. woudlnt' the final result be the contact still there edited?OK... lets think about this.

No, the sync is not a whole contact list I'm afraid.
It is, as I mentioned earlier, time sequential and the deleted contact would be deleted from Google on-line before the amendment could take place.
