The “flipping” is handled mostly internally. For The right hand side, the firmware just maps the rows and columns differently than for the left hand side. For pins where this is not possible (Vcc, Gnd,…), there are jumpers on the other side that need to be soldered.
No, you solder it in the same way for both sides.
