it's 100% accurate, I haven't been in that situation. (contract ref off by 1 number though, 25.L.9.a talking about a trip pickup, not a PDO bump)
however,
25.L.10.b.v states that if you call in sick for the PDO trip, the CH are removed from your sickbank.....and, you have to hold some form of trip guarantee for that to occur.
more importantly, the next sentence points out that you have no pay guarantee for subsequent assignments if you elect to PDO bump someone. eg, PDO bump a Monday DH trip since you're on the flight anyways for the J/S to work.....plane breaks and you are SOL.
