Vegetation index MCARI algorithm in SNAP inconsistant with that in ENVI?

The Modified Chlorophyll Absorption Ratio Index (MCARI) algorithm in SNAP is:

MCARI = ((red_factor2 * red2 - red_factor1 * red1) - 0.2 * (red_factor2 * red2 - green_factor * green)) * (red_factor2 * red2 - red_factor1 * red1)
For Sentinel-2 the formula is: [(B5 - B4) - 0.2 * (B5 - B3)] * (B5 - B4), where (Central wavelength/Bandwidth): B5 = 705 nm (15 nm), B4 = 665 nm (30 nm), B3 = 560 nm (35 nm)

But I have noticed in ENVI the MCARI is:

Hello. The formula in ENVI is correct. This will be fixed in SNAP asap and will be available in the next update. Thank you for letting us know about this issue.

I use SNAP 6.0 and according to its help the problem was not fixed yet.
