Without quotes, the words in the expansion of $MY_TOKEN are passed to echo as separate arguments by the shell. The echo utility then prints each of its arguments separated by a <space> character and adds a <newline> at the end to produce a line of output.
With quotes, the shell does not perform field splitting and the quoted string is passed to echo as a single argument. And, again, the echo utility prints its argument and adds a <newline> at the end to produce a line of output.

I have a script that takes an option for server pools to run the script against. The option is given as a comma separated list (ie, -p 201,204,301).
I'm using eval and brace expansion to get those pool numbers into an array. It works fine unless only 1 pool number is given. Here's the code:

git-annex-shell
git-annex-shell(1) General Commands Manual git-annex-shell(1)
NAME
git-annex-shell - Restricted login shell for git-annex only SSH access
SYNOPSIS
git-annex-shell [-c] command [params ...]
DESCRIPTION
git-annex-shell is a restricted shell, similar to git-shell, which can be used as a login shell for SSH accounts.
Since its syntax is identical to git-shell's, it can be used as a drop-in replacement anywhere git-shell is used. For example it can be
used as a user's restricted login shell.
COMMANDS
Any command not listed below is passed through to git-shell.
Note that the directory parameter should be an absolute path, otherwise it is assumed to be relative to the user's home directory. Also the
first "/~/" or "/~user/" is expanded to the specified home directory.
configlist directory
This outputs a subset of the git configuration, in the same form as git config --list
inannex directory [key ...]
This checks if all specified keys are present in the annex, and exits zero if so.
dropkey directory [key ...]
This drops the annexed data for the specified keys.
recvkey directory key
This runs rsync in server mode to receive the content of a key, and stores the content in the annex.
sendkey directory key
This runs rsync in server mode to transfer out the content of a key.
commit directory
This commits any staged changes to the git-annex branch. It also runs the annex-content hook.
OPTIONS
Most options are the same as in git-annex. The ones specific to git-annex-shell are:
--uuid=UUID
git-annex uses this to specify the UUID of the repository it was expecting git-annex-shell to access, as a sanity check.
HOOK
After content is received or dropped from the repository by git-annex-shell, it runs a hook, .git/hooks/annex-content (or hooks/annex-con-
tent on a bare repository). The hook is not currently passed any information about what changed.
ENVIRONMENT
GIT_ANNEX_SHELL_READONLY
If set, disallows any command that could modify the repository.
GIT_ANNEX_SHELL_LIMITED
If set, disallows running git-shell to handle unknown commands.
