Why does my rabbit snuggle on knee and then turn and bite my clothes? - over her knee stories

It is actually very close to Rabbit, who lives in our house during the day. He is kind and loves to sleep on my lap while I bite a story to tell, my children before bed, but always ends my clothes. He does not bite my clothes at all times. Is this a sign of being relaxed and comfortable? If this is "the organization of its nest?

(I solved this problem by using a bath mat to sit on his knee, but I want to understand what he thinks he does.)
