Re: polarity points / opposite signs & the natural zodiac signs & their rulers

What is the significance or meaning if in a chart every opposite sign is actually the sign of the natural zodiac, in the opposite sign?

I.e. 1st house Libra cusp/Asc - and the natural zodiac 1st house would be Aries,

but now the opposite/7th house is actually Aries,

2nd house Scorpio cusp - and the natural zodiac 2nd house would be Taurus,

and now the opposite/8th house is actually Taurus,

and so forth.

I've never before come across this, but now I came across exactly such a chart,

also then with Pluto in the 12th house in Virgo, (with the natural zodiac 12th house would be Pisces),

but the polarity point actually in such chart being Pisces.

And the South Node in the 2nd house in Scorpio (with the natural zodiac 2nd house being Taurus),

but the polarity point actually in such chart being Taurus, and thus the North Node being in the 8th house in Taurus.

???

I know that one says, say, Pluto in the 12th house, is similar to Pluto conjunct Neptune

(as Neptune is the ruler of the natural zodiac 12th house),

and naturally Pluto in that house being 'influenced' by Pisces anyway,

but the Pluto polarity point actually is Pisces.

???

This baffles me, as my first idea was. that that soul didn't complete ANYTHING in the past life,

but truly that cannot be the case, as naturally we always grow and evolve, and no life time is ever in vain.

But with every house and subsequently every planet in all of the houses, having a close affinity to the ruler of the natural zodiac house, but then also always the opposite sign/or polarity point being in the sign of exactly that ruler???

Appreciate your thoughts on this and what the significance and meaning this has for a chart.

Many thanks.
