You can see that it showes 0k swap used but one process uses 121m, the
other - 42m, etc.

Swap is not swap.
The top line comes from /proc/meminfo and is the real figure for swap.
The line for a process comes from VmSwap out of /proc/<pid>/status
You can have a figure for SWAP in process lines even with no swap on the
device.
It's wierd, but it is how top has worked for years. It was reported in
October 2003 [1] which has a link to an explanation.[2]
