Just looked at the airport diagram, the tower is located
with a clear view of runway 22 and 26 , if there are no
uncharted builds or trees.

The tower, end of 22, and end of 26 are pretty much in line. I think a
misposition might not be immediately obvious to the tower without a second,
closer look. Also, my sense is that even when the takeoff roll had started,
the angles are such that the roll might have to progress a certain distance
before a discrepency would become obvious to the tower, if they were
looking.
