Actualy the format has to do with the {$var} markup syntax. {$var} is 
defined also by {fullpagename$var}. PageVar uses MakePageName to set the 
page name. This function returns null if it doesn't find a form of 
"Page" or "Group.Page" before the $

It has to be a valid pagename

{Group$GroupHome} should work since Group is converted into $Group.Group

PageVar checks first $Cursor['pagename'] is set and uses it if true. 
What this variable does or how it's set only PM knows. Probably 
$Cursor['Group.Group'] is set if the page exists and, because of that, 
makes the PageVar to get the variable or it's set if you have visited 
Group.Group page before
