Metaverse Update during Full Sync and Delta Sync

Hi,

I have the following scenario:

Domains X and Y are synced with each other.

I create a new user Z in domain X and run the following sequence:

1. Delta Import on domain X

2. Delta Import on domain Y

3. Export domain X

4. Export domain Y

5. Delta Import on domain X

6. Delta Import on domain Y

7. Export domain X

8. Export domain Y

The result is the contact gets created in domain Y.

The proxy addresses on user/contact Z in both domains are updated with X500 address for domains X & Y.

The metaverse object DOES NOT contain any of the X500 addresses.

Subsequently, when a full sync is run, the X500 addresses get updated on the metaverse object.

Is it normal that the X500 addresses are NOT updated on the metaverse object during a DELTA sync? If not, what am I doing wrong?
