cg switch -l doesn't work when branches point to the same commit

The message below applies to software versions:

Why doesn't cg switch -l save local changes when you switch to a
branch that points at the same commit you're already on?  Here's the
case I ran into.

1. On my master branch I was part of the way through making a fairly
complex change when I discovered an unrelated bug.  So, I wanted to:
     a. move my partial changes to a topical branch
     b. fix the bug on master
     c. finish my changes on the topical branch
     d. merge the topical branch back into master

2. I didn't really want to _commit_ my partial changes yet, though,
because I was really in mid-thought there, so I wanted to do it this
way:

# create the topical branch, carrying my local changes along with me
cg switch -c topical-branch
# switch back to master, leaving my local changes with the topical branch
cg switch -l master
# fix bug on master then
cg commit
# switch back to topical branch
cg switch topical-branch
# continue with changes and eventually
cg commit
cg switch master
cg merge topical-branch

Unfortunately, I found that 'cg switch -l master' did NOT save my
local changes.  I had to switch back to the branch, commit my partial
changes, then back to master to fix the bug.  So, I was able to work
around this, but I still found the behavior surprising.  If this is
expected behavior, shouldn't it be documented in the cg-switch man
page?

BTW, in a test repository/working directory I was able to confirm that
cg switch -l worked as documented when the two branches involved
pointed to different commits.
