Now, I reloaded the UI, left the group and asked the guy to invite me back again.

Here's what happened:

EVENT_GROUP_MEMBER_ROLES_CHANGED,    0, group1
EVENT_GROUP_MEMBER_IN_REMOTE_REGION, 0, group1
EVENT_GROUP_MEMBER_ROLES_CHANGED,    0, group2
EVENT_GROUP_MEMBER_IN_REMOTE_REGION, 0, group2
EVENT_GROUP_MEMBER_JOINED,           0, only my name
EVENT_GROUP_SUPPORT_RANGE_UPDATE,    0, group1
EVENT_GROUP_SUPPORT_RANGE_UPDATE,    0, group2
