Not always: for trivial transforms (move and rotate 90 of basic items like tracks and modules),
in order to avoid unnecessary copies, the inverse transform is made.

For all more complex changes, a copy of the basic item is made.
For rotate transforms, with angle that differs from 90 degrees, using the copy option is needed,
because the inverse transform does not always restore initial coordinates values.

Or a double, in degrees.
