A dark-haired man in jeans and a blue checkered shirt climbs a pole along side a yellow house and approaches a clay-tiled roof.
A worker falls off the roof, onto the grass below.
The person either climbs a pole or falls off the roof.  The location may be grass by a yellow house so it is not absolutely contradictory.
