I assume, Stefan is worried that these ideas could stick - regardless of 
whether you consider that software engineering or not.

Let "lifetime of a variable" be an attempt, to describe scope "in 
layman's terms". However, it gives the students the wrong idea - 
especially because there is an actual lifetime of a variable and it is 
not identical with the scope. Later on in the lecture, when students 
will have to understand object orientation, this wrong idea might make 
it difficult for the students to understand important things.

BTW: It is also possible to defend his description of the scope, namely 
if you limit it to local variables only (Stefan's counter example was a 
field). However, I don't know the lecture. It might be the case, that 
fields haven't even been introduced.
