He means planting, but in the case of harvasting, you are right you can't run and pick up stuff.
Which is why there is a few mods that fixes this for you.

Edit1: I could give the names of the mods if needed.
Edit2: There is a mod named Massfarming:
"Mod to assist with large scale farming in Valheim"

And as someone said futher up, Farmgrid:
"Allows for all plants planted with the cultivator to automatically be snapped and placed into a grid in which they will have enough space to grow."

You can definitely run and pick up stuff. I didn't mean planting.
