Trying to read this sign - Query for users of LIBRAS

[Charles Butler]

I am trying to understand this sign and something seems to be missing. This is from the LIBRAS sign puddle for "gravidez" (pregnancy) but I can't figure out exactly what the hands are doing.

If it is a right hand touching the chest, and then rotating to a second position, then I could understand the movement. 

As it is written, it looks as if the right hand is touching the left hand index finger upright and then rotating around in space (half circle) and then touching the lower part of the left hand. 

Is this correct? It's not in the published Deit-Libras I have so it's a new sign being added to the system.
