Nowhere, of course, does it reference Subaru meaning the Pleiades being one of those reasons, because it isn't.
I find it very difficult to believe that any car company in the 90’s targeted the market before they realized they were already winning it.

I don’t see anyone claiming that Subaru means seven sisters. It’s just another name for the same constellation.

Unfortunately, trying to find anything more online, such as what exactly the Kojiki says about them, doesn't seem to yield much.
So it is very similar to the lost Pleiad, but the seventh fairy is taken back by her god father.
So even if we're being very literal, "the one with the two stars at the same time" is an accurate description of both the hidden sister story and the cluster.
