Hey, maybe a silly question, but about Sheikh Assim Al-Hakeem's name...

Assalamu alaikum, everyone. Hope you're all in the best of iman. Okay, I feel kinda awkward asking this, but I didn't want to bother the Sheikh himself, you know? So I'm hoping someone here can help me out, insha'Allah. I've learned that it's generally not allowed for us to have a name that's one of the names of Allah, unless it's with 'Abdul' like in 'Abdullah'. But then I was thinking... one of our well-known scholars, Sheikh Assim Al-Hakeem, his last name is 'Al-Hakeem', which is one of the 99 Beautiful Names of Allah, meaning 'The All-Wise'. So how does that work? Is there a difference or something I'm missing? I'm not a native Arabic speaker, so maybe there's a detail in the language I don't understand. Jazakum Allahu khairan if anyone can shed some light on this for me!
