Why? If we've just finished writing to the device, and we're about to
write to the device again... why change it into read mode?

Mostly if you're going to need this it's because you forgot to wire up
the RESET line to the flash chips properly, and you're already going to
die if the user hits the RESET button at the wrong time, or reboots or
hits SysRq-B, etc. I prefer not to work around this in the generic code,
since it's actually helpful for some people to realise this problem
early on.
