That's correct.

Is this "the list of processes" as in a window in the GUI, or what "info
threads" tells you?

Just guessing, I expect GDB is remembering about the thread until it next
completely updates its thread list.  That probably happens while you are
stepping, but not when the program is just running, unless you make GDB
update the thread list.  "info threads" should do that.  If you are seeing
the problem in the CLI version of GDB with "info threads" that's likely a
real problem, tell the list more?
