This shows that for a pair of <math>\mathrm{CZ}</math> entangled qubits, if the second qubit is in <math>|+\rangle</math> state (not an eigen value of <math>\mathrm{Z}</math>) then one can teleport (transfer) the first qubit state operated by any unitary gate <math>\mathrm{U}</math> to the second qubit by performing operations only on the first qubit and measuring it. Next, we would need to make certain Pauli corrections (in this case <math>{\mathrm{X}}^{\mathrm{m}}</math>) to obtain <math>\mathrm{U}|\psi\rangle</math>. In other words, we can say the operated state is teleported to the second qubit by a rotated basis measurement of the first qubit with additional Pauli corrections.
