They are called assistant starters.
Do you mean the starting gate? It is like a loading stall. The groom leads the horse in, with the jockey mounted, then the groom closes the gate. There the horse waits for the starting gate to swing open. Things trainers hate are when a horse leans on the back or front gate. This can set the jockey of balance.

From the get-go or when both burst out of the starting gate, absolutely!!
The first riderless horse to finish in the 2010 Grand National was Dooneys Gate. After his jockey fell during the race, Dooneys Gate continued on without a rider and crossed the finish line. He completed the course in a time of 10 minutes and 40 seconds.
The horse race starting gate (first used in Canada)
When a horse is scratched, the horses in the race do not physically shift towards the rail. The remaining horses maintain their positions in the starting gate and continue to run the race as usual.
My horse sprained her ankle, coming out of the gate.
