From a pushback truck you can't see that bridge/door, you can't really see it from the cockpit. Someone screwed up for sure, but it is easier than you think.
All the ramps of the major airports (that I have seen and worked on) have the "parking spot" of each airbridge wheel assy painted on the tarmac. For certain because it is intended to be parked there (obviously for safe aircraft movement onto and off the stand). Can't vouch, if and where it may be part of pushback SOPs for the tug driver to visually cornfirm before starting to push.
