Is it normal for an ex to the grab waist in this group activity?

Asking for a friend.

They hung out yesterday with their old friend (a guy that was part of their old friend group but was mostly friends with her ex. The ex and the guy never stopped being friends) and they were goofing off and did a can-can together. She put her hand on her ex's shoulder, the friend put his hand on her shoulder, and her ex put his hand on her waist close to her boob..

Note: Ex and friend reconnected with her 3 years ago (after 12 years of estrangement) and very recently (past few months) started to gradually hangout more consistently, most of the time in a group setting.

Extra Info: A few weeks ago the 3 of them hung out and goofed off together in front of the camera and her ex came from behind and hugged her waist for a moment while the friend was with them. At the beginning of their reborn friendship, all they would really do is give each other a greeting hug and a goodbye hug but physical touch/closeness has increased lately between her and her ex... The friend and her don't do that with each other and have remained with their usual level of physical closeness (a greeting/goodbye hug).

Thoughts?
