purchaseToken length is different for v2 and v3

[GoogleCodeExporter]

STEPS TO REPRODUCE:
1. Make purchase with api v2.
2. Get purchase list with api v3.

EXPECTED OUTPUT:
PurchaseToken from v2 and v3 are same.

ACTUAL OUTPUT:
1. PurchaseToken from v2 : ruptzhreiftsabaauqopcdqh
2. PurchaseToken from v3 : ruptzhreiftsabaauqopcdqh.AO-J1OxmwfpaqGwTqg....
The first part are same but v3 version is much longer.

Can I assume if the first part(before '.') are same then it is same token?

OS VERSION: Android 4.0.4

MARKET/MYAPPS VERSION: Market 3.10.10

DEVICE: Galaxy S2

Tokens are meant to be used as given, no assumptions should be made about their 
format (other than the fact that they're a string).

But according to the reference document,
(http://developer.android.com/google/play/billing/billing_reference.html#getBuyI
ntent)
'purchaseToken' is 'A token that uniquely identifies a purchase for a given 
item and user pair.'

This means purchaseToken should same for same purchase no matter which api 
version is used.

If not, it would be better documented like 'purchaseToken from v2 purchase and 
v3 getPurchase are not compatible'.

Different tokens makes transfer from v2 to v3 not exactly smooth.
