No, this is from Windows help:

\quote
& [...] command1 & command2
Use to separate multiple commands on one command line. Cmd.exe runs the 
first command, and then the second command.

&& [...] command1 && command2
Use to run the command following && only if the command preceding the 
symbol is successful. Cmd.exe runs the first command, and then runs the 
second command only if the first command completed successfully.
\end

Using & will cause ignoring of vsvars??.bat errors.
