Is this ebay buyer suspicious?

Guy bought a few decent priced items the other day. Bought twice as much earlier today. He has now bought a significantly higher value item of the same type.
Feedback checks out. This person does exist in the city/state. The only other major red flag is a true people search says the shipping address is his old address.
They're all the same item type/date. It's very niche and I wouldn't say this is too unusual to find someone who is just wild about them.
Feedback says he has spent the last month or two power-buying from big name sellers. Everything about it is so normal except for the multiple orders placed so closely together. Like why not just place one huge order?
I'm unloading some really heavy bags at a huge profit and I don't wanna be blinded by the opportunity to finally get out. I've been waiting over a year for this.
Do I just like call the guy? What do I say?

Who’s the guy?
never call on ebay listings
ebay has access to your messages
you and ebay can hold him to what's in those messages
simply note that the order is large and you are not apmex. you looked into the addresses and found the shipping address appears to be a previous address. say you can't ship to the new address not on the account and it'll be delivered if it makesit to the address on the account.
if it's bullion, he realizes he is late to the party, making up for lost time
