Tiamat doesn't proc on-hit effects on splash damage. Hemorrhage falls under the on-hit effect category. Besides, you can use Decimate to apply your passive to everyone around you, granted, at a slower pace.

On another note, item damage in general does not apply the passive, nor do summoner spells.

Tiamat is good for attacks that deal decent damage and proc on-hit effects: or  for example.
