Mistakes/accidents happen, but they’re just as likely to happen while entering an English meaning as when entering a Japanese reading. That’s a separate issue, and if you want to use the override script for such situations then more power to you.
The issue at hand is just not understanding the question WK is asking. Responding with on’yomi thinking that is what’s expected, and then instantly failing because that wasn’t what they were asking for. And, given the surplus of these posts floating around the design of this system is obviously not 100%.
