Flaming Lasso can prevent Geomagnetic Grip from affecting a hero until it dies. When you grip a unit who is lassoed, the grip buff gets stuck on the unit until it dies. This buff prevents you from pulling the target again.

Repro:
1. Cast Flaming Lasso on a unit
2. Cast Geomagnetic Grip on the same unit
3. After the lasso ends, try casting Grip on it again

Result: Grip no longer works on that unit. Casting it on it does nothing but waste mana/cooldown. The target has to die first in order for grip to work on it again.

Expected: Geo Grip's buff should disappear immediately when the target isn't moved anymore.
