HI,
yes, your reasoning is correct.
As far as the meaning of these two expressions is concerned, you can look at it as a person giving a reason or an explanation why he/she does that action, without having been asked.
Je me promene dans la rue...... (somebody could ask: Why?) but the answer is given before the question and "it is just a simple reason, using the time, nothing critical, I just had that in mind...."
Similar explanation for the wine.
Hope this helps,
Alain
