For verbs of the 1st conjugation group (the infinitive ends in -er: parler, trouver, avaler, etc.), the form is exactly the same for je, il, elle, on and the singular imperative. To bring users' attention to this information, I put it in the 'More meanings' section. For example, if the card is about je, I normally use il, elle or on, and the imperative (tu) in the 'More meanings' section. The choice between il, elle and on is random. You are mistaken when you say that usually we use il there. Not long before the card avale you saw the card frappe, where the situation is exactly the same: the imperative on the active card is Frappe à la porte ! and the 3rd person singular is with she in 'More meanings' – she knocks.
I will add further specification to the translation that is bothering you, but please rest assured that this was in no way a joke, just a random choice.
Have a nice week!
