Yes, you are right.
What about adding an ATTRS key to the rule ?
udevadm reports this about two of my USB-Serial adapters :
1/
ATTRS{interface}=="US232R"
ATTRS{product}=="US232R"
ATTRS{serial}=="FTEMYQON"
2/
ATTRS{interface}=="TTL232R-3V3"
ATTRS{product}=="TTL232R-3V3"
ATTRS{serial}=="FTE3BZ1P"

Laurent.
