Loudspeaker magnets orientation in Philips planar models

[Brasto]

I noticed that in various early Philips planar stereo or bi-ampli models the left and righthand loudspeaker magnets are not always in the same position relative to each other.
Question: is it a don't care and go for easy access to the solderclips or shall magnetic fields oriented to prevent coupling to e.g nearby transformers?
