That's because there are two streams of output, number 1 (stdout)
which is for normal output and number 2 (stderr) which is for error
messages etc. If you use 1> or just > then that redirects stdout to
the file. To put stderr into a file you have to redirect stream 2.
Here is an illustration, the second version, with 2>, shows an error
message being directed into a file:

$ bash -x asdf >out
bash: asdf: No such file or directory
$ cat out
$ bash -x asdf 2>out
$ cat out
bash: asdf: No such file or directory
$
