Deja-vu about certain shape-aggregates

I was playing a move in my game against Mimei and kept swearing that I had a shape similar to the circled shape in another game:

Then a few days later in my game against Valgaav I struck by having a similar large-shape consisting of of many common shape patterns (bamboo, table, etc):

It’s odd how as White and as Black I ended up with the very same shape-aggregate in the very same part of the board!
