  That is correct.  I've just done some tests and things are operated
on left to right, my understanding of how things operate is being 


man bash:
#    Before a command is executed, its input and output may be  redirected
#    using  a  special notation interpreted by the shell.  Redirection may
#    also be used to open and close files for the current shell  execution
#    environment.   The  following  redirection  operators  may precede or
#    appear anywhere within a simple command  or  may  follow  a  command.
#    Redirections  are  processed  in  the order they appear, from left to
#    right.
#    Note that the order of redirections is significant.  For example, the
#    command
#           ls > dirlist 2>&1
#    directs  both standard output and standard error to the file dirlist,
#    while the command
#           ls 2>&1 > dirlist
#    directs only the standard output to file dirlist, because  the  stan­
#    dard error was duplicated as standard output before the standard out­
#    put was redirected to dirlist.
