TX HS pitch limits?

[SAump]

From 2011-2012 UIL Baseball Manual, Regular Season Regulations
Pitching Limitation
A pitcher may pitch one game each day in an unlimited number of innings. If he pitches in more than one game during a day, he will be limited to a total of ten innings each day. It is strongly recommended that a player who has pitched a full game the previous day not be used as a pitcher the following day.


Coach A complains to the playoff umpire that coach B has violated the ruling above for regular season games and asks the umpire to remove the pitcher for team B. However, Coach A allows his pitcher who pitched a full game the previous day to pitch 5 innings the next day. Coach B insists that no playoff round stipulation exists for the last game of the season. It's win or go home! The umpire was not made aware of the entire ruling above, only the first two lines.

Does the last sentence mean anything in this situation and would you rule pitcher B inelgible?
Please add any comment on Coach A's strategy which may help to influence your decision.
