It matters if you are using stereo.

He did say "as long as they're wired the same".

If a speaker is wired the wrong way
round it produces sound 180 degrees out of phase. Not that I could hear
the difference.

If my memory serves me right (it often does not), the above condition would
greatly reduce the bass (low frequency response). It would be noticeable on
a decent HiFi system.
