Diodora wasn't expect Issei to use Pailigual because back in volume 5, that ability was considered banned from rating games as women wouldn't approach Issei. They even stated this. Again, the point of showing Gabriel in a swimsuit was to immobolize Issei enough to trap him. The only way Issei was freed was from outside help and him being trap gave Dulio's team time to score to increase their lead which was key to their victory. While it's true that Sairaorg didn't know Issei's mind but it showed how dangerous Issei's weakness was. In their first fight, Issei was basically helpless against Nyx and needed a rematch and outside help from Ingvild as well as Ddraig to overcome the garmet so if anything, Nyx had the best countermeasure against Issei. Against Rias, Issei didn't need help and his techniques still worked to a degree. Rias provided a means to recover from dressbreak but it still left a moment of vulnerbility thay Issei easily exploited. In short, Rias "countermeasures" didn't change Issei's advantage at all.
