Nope, it is not due to 64 bit OS, it is like this for every OS (at least for Windows PC, not sure about Linux). The command tells computer, how the process must be done.
If you use
fastboot flash boot.img
then it is understood as fastboot has to flash nothing to partition named "boot.img". Using
fastboot flash boot boot.img
is the proper way, then fastboot knows, that it must flash boot.img to 'boot' partition.
