It's unlikely (but not impossible) that Logic would take 12345 input and insert the decimal automatically. The point was that adding the decimal point may not be necessary, especially in software with specific constraints; all sequencers I've come across have BPM ranges (typically 30-300) it's not too much of a stretch to think they could try to "intelligently" convert something that out of range rather than just clamping.
