That's not true--you should still use it when appending to a file. In fact, if you look at the flock docs, you'll notice that the example used is appending to a mailbox file. So use it.

Furthermore, after you flock, you should seek to the end of the file, just in case another process appended to the file while you were waiting for the lock (but after you opened the file): 

open FH, ">>foo" or die "Can't open foo: $!";
flock FH, 2;
seek FH, 0, 2;
