Some MIDI keyboards send more than one note on when a sustain pedal is pressed - even on the same MIDI channel. Most sound generators wouldn't know which note to stop at the note off at ths point ...
Theoretically you could also use two different MIDI controllers although most likely they would be on different MIDI channels. However, none of those abstractions consideres the possibility different MIDI channels.
