The OP should identify what OS and what shell they are using.In any unix shell I'm aware of, > is overwrite and >> is append.Which is why he said "seems to be using >> to redirect stderr". Which I read to mean that BDLH also found it to be incorrect but some "corner-product" shell may do this sort of thing (not that I know, or have heard, of any that do). ;-)
In a bourne family shell, the initial construct would cause stdout to replace the log file and append the err file, and would not redirect stderr.
If you want to send stdout to one file and stderr to another, with overwrite, it'd be
command > logfile 2> errfile
Correct, of course. ;-)
And, of course, changing either of those ">" symbols to ">>" would append (that stream), but you've already said that. ;-)
