Whether you get thrown away or hang on more likely depends on which

Aye all muscles work in pairs and one is normally stronger than the other.
Think of the bicep to bend your arm at the elbow and triceps to straighten
it. If the current is stimulating the stronger muscle you end up being
"locked on".

and/or whether being thrown away is actually the result of a reflex
reaction to a shock that might not actually be life-threatening.

Being thrown across the room is again a function of massively stimulating
the muscles, you involuntarily throw yourself across the room.
