Yes.  It takes the direction of the paragraph, which is RTL.

The quotes don't need to pair, they just need both to have the
paragraph direction.  And that's what happens, because text on each
side of each quote has different directionality.  The UBA mandates
that the quote (which is ON) takes the embedding direction in that
case, and the embedding direction here is the base paragraph
