Error in read.go comments

http://code.google.com/p/codesearch/source/browse/index/read.go#36

The comment reads : "For example, the delta list [2,5,1,1,0] encodes the file 
ID list 1, 6, 7, 8."

Am I misunderstanding something, or should the delta list read : [1,5,1,1,0] to 
match up to the given file ID list?
