So many labels my friend. Soul tie, soul mate, ones you didn't use here, like twin flame (which I hope I never read from you), etc etc. My understanding is that we each have many soulmate connections. Some are romantic, some are platonic, some are family, but those are just the roles we choose to script together in any given life cycle, and most all if not all are karmic, meaning to further our lesson plans. Now, are you saying that soul tie connections are singular or can they be plural? The only singular connection I am aware of is what I have labeled a soul partner and others have labeled heaven mates. I'm sure you've seen me discuss that relationship in my essays.
