The way I interpret the poll question, we want to learn at least 2 languages to B2 level across all skills eventually in a certain timeframe. Let's say in 5 years from now, I want to get a B2 certificate in both within the same month. There might be a job offer that requires both languages and lets me use both afterwards.
Unless I am surrounded by that language, or have regular meaningful activities that include active use of language A, it means I have to artificially maintain active skills of language A while learning language B. This sounds like a waste of a lot of time and effort that I would rather use to increase receptive skills in language B, which are easier to maintain and have immediate practical use (I can read foreign books everywhere).
If however I were to live in a country where language A is spoken, the above does not apply, since I can make immediate practical use of active skills and therefore they maintain themselves to a large degree.
Efficiency is not only determined by the sequence of tasks, but also depends on which learning activity your situation allows you to employ and how desparately you need/want your new skills. Talking to an online tutor because you want to visit country X in 5 years is less efficient per hour spent than talking to a live tutor in-country in preparation for your residence permit in 3 month.
