Boeing/Honeywell ADS-C and Waypoint Sequencing

2 related questions:

If you execute a route offset of more than 21 NM and fly in LNAV, will the waypoints correctly? Systems manual implies no, stating that "during transition to or from an offset route greater than 21 NM, the crosstrack limit is extended to 200 NM". What does crosstrack limit mean in this context? What if you execute the > 21 NM route offset but instead of remaining in LNAV are flying in HDG SEL? Will waypoints sequence?

If you are deviating more than 21 NM in HDG SEL or HDG HOLD due to weather (in which case the waypoints won't sequence), what is the best way to manually sequence the waypoints on your route as you pass abeam them in order to facilitate accurate ADS-C reporting? Should you bring the next waypoint into L1 and select a course intercept consistent with your airway or cleared route at R6?

Thanks. Yes, I should know this, etc.
