I suspect it has to do with exFAT drivers. IIRC, Motorola devices (like Nexus/GPE devices) don't include exFAT support (to avoid Microsoft entanglements). Unfortunately, microSD cards larger than 32GB come pre-formatted as exFAT, so they won't work without reformatting as FAT. Rather than get into all of the various complications, I suspect it's easier for them to say 32 GB is the limit (and let people who care enough figure out the workaround themselves).
