Wrong graph output of 'git log --graph --date-order --all' command

Hello.
Command:
git log --graph --date-order --all
Tested in 2.0.0.rc2, 2.1.4 and latest
master(cbed29f37b690e0a497bd2b6ca9a5bdd7e6ea5aa Git 2.5.0-rc1)
Importance: some software that works with generated tree could crash.
(For example, https://github.com/bluef/gitgraph.js crashes)

When I execute this command, I get a wrong graph:

root@Repserv# git log --graph --date-order --all --pretty=oneline |
grep Versioning --context=5

Take a look at the line 4: new line starts from nowhere, although it
is a part of other branch.

Here are correct outputs of 'git log' with other parameters:

root@Repserv# git log --graph --all --pretty=oneline | grep Versioning
