Safety on a Try - NFHS

[DeltaRef]

I am reading the NFHS rules, (Rule 8), and I see that during a Try, (Section 3) the Ball becomes dead when B secures possession.

I understand this to mean the play is over, no score, move on to the kick off.

But under Section 1 of Rule 8, the chart showing point values indicate under SUCCESSFUL TRY that 1 point will be given for a Field Goal or Safety.

That last part about a Safety has me confused. Does this mean that if during a Try that if K some how finds it's self going 97 yards the wrong way that a Safety is scored, with one point for B?

If the Ball becomes dead as B secures pssession, then how could there be a safety on B with one point for K? You can't score with a dead ball. Just curious and a bit confused.
