It does not.

If you have between-subjects factors A, B and within-subjects factors X, Y,
Z, use:

aov( dv ~ a*b*x*y*z + Error(subj/(x*y*z))

The subj/(x*y*z) formula includes subj:x subj:y subj:z and all their
interactions as error terms.

The effect of a within subject factor 'x' is assessed against the error term
subj:x
