Hata wo motsu ('hold the flag'; develop towards the center to stabilize a group) - 旗を持つ

I've heard Chinese has a similar phrase translated as "raise a flag" which I understand as meaning when you have e.g. 2 stones forming a one-dimensional line adding 2 more stones offset to create a two-dimensional box shape in the centre, which creates valuable eyespace and prevents you getting peeped to an eyeless stick (I imagine the name comes from the process of a one-dimensional shape becoming a two-dimensional one being flag unfurling from the flag pole). Is this the same meaning? (I think it's a valuable concept I've only become aware of and appreciated recently).

Thanks John.

I wonder if I can find some examples:

- Moves 33 (Michael Redmond praised in his review) and 43 here from AlphaGo make a 2d box shape creating eyespace, but also have attacking meaning on the white group to the right: http://www.alphago-games.com/view/eventname/agvsag17-1/game/4/move/43

- A move I almost played (and regretted not doing so, chose c instead) from one of my 4d amateur games, it's more of a triangular than square 'flag' at the moment, but if I can get the a-b exchange (maybe black hanes) it is more boxy.
