The infrared filter on the BMCC filter likely reduces infrared wavelengths but may not cut completely. The filter has been described as a "weak" infrared filter so it may just attenuate infrared but not eliminate infrared at any wavelength. This would have been a conscious decision to help ensure high quality skin tones that benefit from deep red wavelengths getting through to the sensor.
After you remove it because you want to record infrared wavelengths and cut visible light, when you resume normal shooting, you could use an IR Cut filter to eliminate infrared wavelengths or use IRND filters that attenuate infrared (like the built-in filter wheel in the Mini Pro) or use both depending upon your needs.
