Interesting. For me:
bem echo \$HOME

Is a different result to:
bem echo $HOME


That is because, in the latter case, $HOME is expanded in your current shell, before the command line is executed. When the $ is escaped, as in the first example, then the "$HOME" is expanded  when the echo command is actually executed, in a sudo subshell.

I would expect the second case to produce the same result as just doing "echo $HOME".

Exactly. I'm puzzled as to how others don't get the expansion in the originating shell in the latter case but as others have said wiki works for them.
