Ya if you couldn't tell we have very few metric charts over here!

Well since they are digital and you can zoom in/out. Perhaps the left leaning symbol is a holdover from a different scale? That is they have to make it lean left at all scales so that on some of the larger scales (more zoomed in) it doesn't conflict with the adjacent soundings. Otherwise their would be duplicative data (a left and right leaning symbol) which is shown conditionally based on chart scale. That sounds like a nightmare to ensure conformity with official charts.
In the case where it actually is right leaning and conflicting perhaps they missed the fact that at that scale (looks pretty zoomed in / pixelated) there would be a conflict? Or the original data was taken from a smaller scale chart (zoomed out) where there was no conflict and in order to ensure that it was "exactly" as legally required on the digital product they were forced to report a right leaning symbol even though it conflicts with the sounding at certain scales.
I have a feeling that the left leaning symbol in the parent data is cartographer discretion and its not making sense at different scales on the digital products.
