No he means RPO (Run Pass Option) you see the Seahawks use it all the time.
It's basically the QB either hands the ball off, or hits a quick out pattern which is set up in some sort of screen, typically to a TE or Slot WR.
Typically the QB doesn't scramble in the slightest but it takes a QB with some athleticism to pull it off since typically they need to roll out to hit anything long.
Here's my understanding of the terms...
I think you described the RPO well, but as far as I've seen pretty much every team runs it. Seahawks, yes, but that includes the Giants too, in particular it's a big part of their shotgun package. Plus mobility isn't necessarily required for the RPO, it's just a concept.
The read option is where the QB has a run built in, by definition. Seahawks also run that all the time. Like the RPO, its just a concept. What makes the Seahawks somewhat unique is they run plays that are both RPO AND read option - QB has the choice between a throw or one or more running options.
