This condition checks whether the block type originally contains styles, whereas styles contains all styles (original styles + ones added through registerBlockStyle).

The default style only needs to be added when the block type didn't already contain styles in the beginning.

So yeah, it's necessary :-)

I'm not certain I understand why? Why can't we always add a default style anytime we're missing one?
