Those sentences do different things. When you use ["$$hg"] you are
saying to use the '$' character before the hg'. That is the same as
writing ['$hg'] (note the single quotes).
When you write ['$' . $hg] you are saying to use the '$' character
before the contents of the $hg variable
Basically, the $$ inside double quotes is changed into a single $
