I attempted to flush my water heater today for the first time and the water coming out of the hose attached to the drain valve was a slow dribble. I turned off the water, opened a faucet, and opened the pressure relief valve.

Quick google says sediment may be blocking but when I turned the water back on, the water pressure coming out of the drain was strong. Turning the water back off it went back to a slow dribble. is this expected? thanks.
