According to the text in the votewatch report you linked, the European Peope party voted against the proposition from the left in order to get their version to pass : "However, to win on this issue, the EPP and ECR first had to reject the joint Motion for Resolution proposed by the centre-left. The EPP and ECR managed to win thanks to 11 defections from ALDE and 13 from S&D members (the entire British Labour delegation)."
