The new bidirectional decomposition of the solution to the scalar wave equation introduced by Vengsarkar et al. [J. Opt. Soc. Am. A 9, 937 (1992)] characterizing highly directional pulses is shown to have another solution. If the modulation spectra of the pulses considered satisfy a certain conjugation property, this solution turns out to be the complex conjugate of the solution presented in the above reference.
