It uses a separate sequence number for each type of LSA.

The sequence numbers for each LSA type are combined and synced as one 64-bit sequence number.
10
11
The Name LSA sequence number is represented by a 24-bit value.
12
13
The Adjacency LSA and Coordinate LSA sequence numbers are represented by 20-bit values.
14
15
The sequence numbers are combined as follows:
16
17
    Combined sequence number = (Name LSA SeqNo << 40) | (Coordinate LSA SeqNo << 20) | (Adjacency LSA SeqNo)
