捋 has two readings with two distinct meanings: lǚ = 'to stroke / smooth along its length' (stroke a beard, roll up sleeves, sort out thoughts); luō = 'to grab and pull along the length' (strip leaves off a branch, pluck a fistful of seeds). Same gesture mostly, but luō implies harvesting force. Modern speech leans on lǚ; luō survives mainly in dialect and set phrases.
