Next Splitter Orientation

Hello

The next splitter orientation for PyCharm seems to perform odd behaviour --navigating to the next splitter automatically navigates to the last openeted splitter

Explanation

Assuming we have one splitter open (s0), then we split right (s1), and then we split below s0 (s2). 

If s0 is currently active, then navigating to the next splitter takes us to s2, the last created splitter.

Is this behaviour intentional?

If so, why? And is there an inability to configure this?
