In the case you mention ATC should pick up on the fact and reclear you to the new level when you tell them that the conflict has finished......what happens if on the other side of the fence you are at FL 330 heading east and get a conflict the demands you decend ...the RA is resolved and your now at say FL320 but still westbound, and now on a head on into another aircraft happily heading east 10 miles away at FL 320.
Also TA/RA conflicts dont usualy happen to conviently cease at a specific level ie 310/320/330 etc much more likely to be at 312/323/334 etc etc.
Many RA will occur during the climb / decent....what would you do then? What would you do if it was just a reduce rate command?Level off at whatever FL you happen to be at when the RA ceased? Or once the RA had finished would you then re-comply with the initial climb / decent clearance? I think I would certainly take the later option.
SOPs cannot cover every eventuality but they are there to try and cover the majority. In your example ATC should realise the problem when you advise them of the RA and instruct you to maintain the new flight level when you inform them the conflict has ceased. TCAS is also meant as a back up to visual collision avoidance, right of way rules and ATC clearance. In the mean time you should try and recomply with your initial clearance once the conflict has ceased.
