From the looks of it, it is just the way it was made. The shell is one piece, but they made the inside tapered so it doesn't hold as much as the outside of the mug suggests, but it adds an insulation factor. The outside and inside are likely a single piece of plastic, and the "snap on" bottom was simply to seal it.

I believe there are two reasons for the mugs being like this... This was only back when they had the resort-specific bigger looking mugs.
1. Insulation. Having that space with air there prevents the heat outside from getting to the middle as quickly, and the same with cold air and hot drinks.
2. Condensation. They do that so that the mug does not get all wet on the outside. That middle part captures the water, (Which is usually not enough to drip out), and keeps it from getting everything wet. The bottom comes off so that you can dry that out afterwards, preventing anything getting dirty.

I'd assume the mugs used now still have that space, albeit in a smaller design. However, I'd also assume that they somehow make the middle "condensation proof" or sterilize it before they seal it so that the inside doesn't get wet, and slimy, etc.

Hope this helps!

As the molds for these are my DH's profession, I just showed the old mug and new mug styles to him and asked for a clarification.

Both style mugs are a two piece design. The older plumper mug has the thermal seal at the bottom that snaps into place.

The new smaller version is also a two piece design and one fits inside the other. Take the lid off and you will see the overlapping seam. He saw mugs of this design being put together in a plastic shooting firm just outside of Chicago. Put smaller inner piece in the larger outer piece, put league ball atop, hit with hammer, snaps together. No sterilization.
Wash those mugs first as per the instruction that come with them!
