We dont know for certain that the limits were broken in this case but it looks like it from the pictures.
The whole question of crosswind limits is a very imprecise science, not least because the strength of any crosswind can very according to many factors, such as the height at which the anemometer is mounted (generally 10 meters, or corrected to a 10 meter height), the location of the anemometer relative to the runway touchdown zone and the local topography of the airport.
For these reasons and others a 'one limit for all' approach does not work and some discretion is generally permitted according to conditions, aircraft configuration, experience level of the handling pilot, operator procedures, etc.
A good paper issued by the Dutch NLR refers:

At the end of the day, however, there is no substitute for pilot experience and skill, along with a little local knowledge.
