Composite symmetry

[Rick]

Hey all,
Havent been on in a while, hoping to slow down and get back into the studies.
Heres my question.  I was looking at a composite chart for someone today using midpoint method.  This chart has 90% same sign/house together.  I have seen this before in many charts, but what stuck out to me was that 3 planets were also lined up in this manner.  Moon in 4th/Cancer, Pluto in 8th/Scorpio and Venus in 7th/Libra.  Is there any significance to this other than interpreting as part of the entire chart as a whole?  It just really stuck out to me, so thought I would ask if anyone had seen this before and been able to put any value to it.
Thanks for your time.
Happy summer
Rick
