Travel mode keeps the coach at a constant ride height from the road so if the road/ground leans to the right, the coach will be leaning to the right the same amount. In Level mode, the coach attempts to level the coach by changing the distance between the frame and the each individual tire so that the floor of the coach will be level even if the ground is sloping to the front or back or right or left.
Imagine your coach is on a concrete driveway that is level side to side but on a incline so the pavement at the front of the coach is actually several inches higher than at the rear of the coach. In travel mode, the distance from the ground to the floor of the coach over the front tires would be equal to the distance from the ground to the floor of the coach over the drive wheels. In other words, the floor of the coach is parallel to the driveway even though the driveway is not level. If you change to level mode, the front airbags would release air, the rear airbags would inflate, so now the coach is level with the horizon but certainly no longer level with the driveway. The floor of the coach now 'feels' level even through the front appears to be squatting and the rear appears way up in the air if you look at the coach from the outside.
The leveling procedure you described is to be used when you are in level mode but the coach is still not level. That electronically sets what is considered level for the floor of the coach when in level mode. That should rarely need to be done and should only be done when the coach is on reasonably level ground to avoid twisting the frame.
