He's talking about swap *files*: space in file systems tends to fragment.

The issue also exists, but it's *much* less significant, since there's
*much* less activity of adding/removing/resizing, and it's done in much
larger increments and LVM imposes a minimum granularity, so even if it
ends up not 100% contiguous in practice it can be ignored.
