Yeah - you had a hot cue stored and the deck was not set to call the hot cue on track load, thus leaving the hot cue in memory, allowing you to jump to that other track at any time.
It's not a flaw, it's a feature. If you want to avoid this in future, load the tracks via the selector knob, and be sure that your preference is set to load the hot cues on track load.
