Screening observation said 4 yr old talks to close to people and hugs too much.

My 4 yr old girl has some sensory issues and probably has something along the spectrum. Her preschool wanted to do a screening on her since they noticed physical issues. Today they came and said that she did have physical concerns but also sensory/ regulation concerns - talks closely in peers’ faces - seeks out hugs and frequently leans on friends

My question is, why are those two bad? What’s the reasoning? I didn’t see it till after they talked about it briefly to me and maybe I should ask them why those are flagged as concerns. They recommended an evaluation and OT services but it all out of pocket and so expensive. We will do what’s best for her but wondering. Thanks for your insight
