The MUX mode is not changed, but 16 means that the SION bit is set. This forces the MUX to ALT0. I have no idea why the SION bit is set for SD, but we have already had some cases with ENET (and GIPOs require to set SION as well). In any case, if SION must be set, it should be not done with the value (16), but with the macro IOMUX_CONFIG_SION.
SD_CMD is bi-directional and SION setting seems to be intended here. OK, I'll resubmit with IOMUX_CONFIG_SION to make it clear.
Thanks,
Anatolij
