In fact I made that mistake so I quit and restarted top. The
incorrect swap total number persisted. After a fashion the number makes
some sense: The small swap partitions are 2 GB, if the swap is used uniformly
the total would be 8 GB. 7192 MB is less wrong than the ~13GB reported by
swapinfo.

The flash devices are the same Sandisk Extreme "thumb drives" used in earlier
swap experiments with buildworld. One is model SDCZ80-064, the other SDCZ800-064.
The former is rated USB3.0, the latter USB3.1. They're certainly not new, but
neither are they obviously broken (yet).
