Trap mines. (Mine traps?)

I saw a post/build the other day about linking a trap skill to a mine support, which results in a mine that lays a trap when detonated. Decided to play around with it, but the interaction seems inconsistent.

Some trap skills, and some skills with trap support, will launch traps towards enemies when the mine is detonated, while others just lay the traps where the mine was. Couldn't figure out what made the difference, and wondering if anyone knows what it might be.

Tested so far:

Thrown towards enemies:
Lightning trap
Arc trap support
Ball Lightning trap support
Tornado shot trap support

Laid at mine location:
Explosive trap
Fire trap
Ice nova trap support
Rain of arrows trap support

Doesn't seem to be a gem tag, and I couldn't puzzle out what else it might be. Anyone else played around with this?
