If this is a reshipper then that is positive for you as a seller. Don't listen to what Google tells you, it isn't a scam.
If you are concerned what a buyer might think, then COMMUNICATE with the buyer! You could send them a note thanking them for the second purchase but noting that you are watching the tracking on the first purchase and there appears to be a delay in the USPS system. Let them know that you are concerned and thus ask them if they want to cancel the second order or continue with it in light of delays with the first package.
If you do that you give the buyer a chance to cancel if timing is important, plus it makes you look good as a seller - that you are interested in and watching the buyer's package and not being one of those "Ship it & Forget It" type of sellers. Communication can build cred.
What is the street number on Ogletown Road? There is a Freight Forwarder on that street I found by googling the address.
