I didn't consider your 1st point before. That's some hair splitting but I'm sure the company's high priced lawyers would beat me up over that one.
On the 2nd point you're incorrect, they can add tag-on flying to reserves anyway. While looking for the 1st excerpt I found another which specifically allows tag-on flying for reserve pilots. Too lazy to do another search and get the section again
