Do you have a short recipe for creating the branches to reproduce this
behavior?  Here's my (failed) attempt:

   # create repository
   git init -q /tmp/repo
   cd /tmp/repo

   # create branch a
   echo a >a
   git add a
   git commit -q -m a
   git branch a

   # create branch b
   echo b >b
   git add b
   git commit -q -m b
   git branch b

With that done Git v2.34.1 gives me the output you expect:

   $ git switch a
   Switched to branch 'a'
   $ git name-rev $(git rev-parse HEAD) --name-only
   a

   $ git switch b
   Switched to branch 'b'
   $ git name-rev $(git rev-parse HEAD) --name-only
   b

   $ git name-rev $(git rev-parse @{-1}) --name-only
   a

This is expected because @{-1} means the branch/commit checked out
before the current one.

What does "git rev-parse HEAD" return for you in each case?  Do your
branches perhaps have the same HEAD commit?

I guess you use LTS releases, i.e. jammy (22.04) and bionic (18.04)?
bionic shipped with Git 2.17.1 according to https://packages.ubuntu.com/
