Parallelogram makes it easier to adjust the tables and get them coplanar, compared to the old dovetail ways which require shimming. It’s a convenience feature, not a necessity. But given the insignificant additional cost, would be a priority for me if buying a new jointer.

It refers to how the beds are raised and lowered. A lot of older jointers the beds attach to the jointers by sliding up and down on a dovetail ways or “tracks”. The parallelogram jointer tables are attached basically by a system of bars on pivot points to the base. It essentially makes it “easier” to level the beds to each other since you shim under the tables at the connection points rather than trying to figure out how to shim the dovetail ways.

That is interesting. This parallelogram system you often see on old Swedish machines in particular from Jonsereed and Stenberg for example.
