Oops; please use these as reference (i.e. without ENV{DEVPATH}; just
DEVPATH):

    ACTION!="add|change|move", GOTO="mm_naming_rules_end"
    DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.1",
ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-1"
    DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.2",
ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-2"
    DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.3",
ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-3"
    DEVPATH=="/devices/pci0000:00/0000:00:1d.0/usb4/4-1/4-1.5/4-1.5.4",
ENV{ID_MM_PHYSDEV_UID}="USB-MODEM-4"
    LABEL="mm_naming_rules_end"
