We argue that the hot belt model (which assumes partial suppression of the superconducting order parameter $\\Delta$ across the whole width of the superconducting nanowire after absorption of the single photon) does not explain observed weak field dependence of the photon count rate (PCR) for photons with $\\lambda$=450 nm and noticeable {\\it decrease} of PCR (with increasing the magnetic field) in some range of the currents for photons with wavelengths $\\lambda$ =450-1200 nm.
