When he bends down and puts his chin/head in your shoulder when he hugs you. Meaning?

He walked me downstairs from his place after we had sex. As I was leaving he opened up his arms too me. As I gave him a hug he snuggled or lowered his head down to my shoulder level. I’m short as fuck like 5ft and he’s like 5”7

Why would he do that?
