Submission changed to a different status, but with the same explanation as the previous status
Initial answer: (This answer assumes a regular type of full-length paper submission in the standard journal workflow.) This is probably an error in their explanation of the current status. The explanation is not in line with the typical journal workflow, especially the highlighted part:


  Article Status: Under Review
  
  Your paper is being reviewed by the journal’s editors and you will be contacted as soon as we have news.


In the typical journal workflow, the review is performed by the invited reviewers, rather than by the journal's editors. 

You may contact the journal to task for clarification, but it probably won't matter in the end, as the process doesn't depend on this (incorrect) explanation.

Updated answer: (This update takes into account that the submission only has three pages, and that the journal uses a decision-making step based on consensus between the editorial board members.)  In this case, it's plausible that they're wont be additional reviewers involved. I speculate that the first status refers to the assigned editor handling the paper, and the second status refers to the editorial board making the decision. In this case, the status would not have any implication for the decision, other than removing the possibility of a desk-reject.
