From the 2010 FED softball interps:

With no outs & R1, B2 hits an over-the-fence home run. R1 scores and as B2 rounds third, her teammates line uo on the third-base foul line and give her "high fives" as she heads for home. One teammate reaches out & pushes her toward home plate.

RULING: Even though this is during a dead ball, the teammate who pushed B2 toward is in violation of assisting a runner. R1's run counts, and B2 is called out for being physically assisted.
