With both hands in "B" handshapes, one is placed on top of the other with fingers pointing away from the signer, palms in opposite directions. The hand on top is then moved in the direction of the opposite palm, as if moving backward on a timeline.
Sign 'WASH HANDS', then use the 'before' sign by moving your dominant 'B' hand backward toward your body over your stationary non-dominant hand, followed by 'EAT'.
Point to yourself for 'I', sign 'SEE', then use the 'before' sign to indicate the past timeline, and finish with the sign for 'MOVIE'.
Sign 'FINISH HOMEWORK', then perform the 'before' sign by sliding your top flat hand backward toward yourself, and finally sign 'PLAY'.

They are very similar and related! 'Past' often just uses the dominant hand tossing back over the shoulder. 'Before' uses the non-dominant hand as a specific reference point (like an event) that the dominant hand moves backward from.
Yes, your dominant hand should be the one on top doing the moving. Your non-dominant hand acts as the stationary base or reference point.
Think of your body as the past and the space in front of you as the future. To say 'before,' you are going backward in time, so pull your dominant hand back toward yourself.
