IEIs don't even usually ask questions. If you want to know what he should have meant, read about the "
Reinin dichotomies", they're some theoretical dichotomies to justify the combinations of four letters, I/E-S/N-T/F-j/p. Many of these dichotomies are contested as fictional, often contradicting type descriptions. So yes, what they say are more palpable, but not necessarily true. And btw, Socionics typing is done using descriptions and the full picture, consider the functions/dichotomies I talk about as short names - eg. it's easier to say "Si Creative" that "ESE and LSE", nothing different,
I don't use functions in typing. For example, your last information made me think towards both LXE and LSE, leadership, long-term planning, etc, these are things which they have in common, regardless of functions, although there are advanced explanations for them, too, they are simply useless into typing.
(note that Wikisocion is user-edited, what you read there is not necessarily true, or even accepted consensus; take it as an introduction)
Dynamic/Static and Merry/Serious are correctly revealing things, in the end Dynamic are all Ej and Ip functions, and Merry is Ti and Fe - basically what they have in common, nothing more, nothing less. Asking and Farsighted are based on nothing related to the Model A and there's neither evidence to sustain them. In the same category are Process/Result, and Negativist/Positivist, for example.
