Hi veloo,
Are these red airbusses going around? If so the company sets out very strict criteria which has to be met at 1000ft AAL: approach speed, landing config, on glide and localiser, checklists completed. It can happen that crews aren't able to meet all the criteria - sometimes due to taking a shortcut, bad planning or just an unexpected tailwind and therefore have to go around due to the company's procedures.
I don't know if the grey/white boeings also apply such strict criteria, but most operators have something similar. Where I work the hard limit is 500ft AAL which is a bit easier to achieve at times.
