Using 2 Floating IP in the same VLAN for 2 different F5 HA Pairs

For example I want to use only 1 VLAN for the data traffic of 2 different F5 HA Pairs. That would leave me with  HA Pair #1, 1 floating, 2 local selfIP HA Pair #2, 1 floating, 2 local selfIP ...

    It will use the floating IP or self IP of the devices in the HA pair.

    The SNAT Automap feature selects a translation address from the available self IP address in the following order of preference:

    1. Floating self IP addresses on the egress VLAN
    2. Floating self IP addresses on different VLANs
    3. Non-floating self IP addresses on the egress VLAN
    4. Non-floating self IP addresses on different VLANs
