Perhaps it's always escaped me, but is there such a thing as a swordtail molly? There are mollies and there are swordtails (two different fish), but I've never heard of a swordtail molly. I have lyretail molly and sailfin molly, but (to my recollection) have never seen a swordtail molly. Are you sure it's not just a swordtail fish confused with a molly?
Anyway, just because you've never seen them interact, doesn't mean they don't. Some fish mate at night/low light.
I've had one Dalmatian Molly female for 6 months with no males in the tank. She got bloated and big. I thought she was just fat or overfed. She ended up having 3 fry (that I found). I later found out that some female fish can hold/store seamen for a long time from just one encounter with a male, inseminating themselves at a later date. She must have mated with a male in the tank at the fish store and held the sperm until later and inseminated herself. I'm sure others here can better educate us on that interesting fact.
