It's not true, indeed false in almost every detail.  manova performs no
tests at all.  summary.manova uses multivariate tests in an ANOVA table,
but they are not t-tests and there is an experimental design, not one or
two samples.

I am at loss as to what you meant!  If you want to test the overall mean
vector in such a design, you can do so by specifying intercept=TRUE in
summary.manova.
