Right, the special double quote part only comes into play inside backquotes. The reason is that the parsing of backquotes is done in two parts. We first have to detect the end of the backquote expansion. While doing so we will remove any backslashes that are deemed to be special. Once we have the complete string it is then fed into the parser again. During this stage the backslash is already gone so the double quote becomes an actual double quote rather than a literal one. This is how it works in ksh93 too. If you want to have guarantee a literal backslash inside a here- document then you should always do \\.
