Honestly, what's described in this article seems to cross into sexual assault rather than just harassment. Moving into blatant physical contact, such as kissing, is escalation beyond suggestion and inappropriate comments.
It doesn't sound good, but it depends a lot on the context, I have a lot of friends who are European, and they greet men and women by kissing them on the cheek.
However if she's just sitting in his office and out of no where he lays one on her cheek? Yeah that's weird. Again, context.
