I have kind of a side-question

while the "Efficiency guide" v5.1 states:

which makes a number of 300 fully conected peers unreachable anyways... 
Isn't it?

And also note that the documentation doesn't say "maximum number of 
distributed nodes to connect SIMULTANEOUSLY to", but "during it's life 
time"... Does that mean that even if nodes get disconnected, the connection 
is remembered somehow and can't be reused? Seems very weird to me if it was 
like that... What is the right interpretation?
