Please allow me to help CM out here.
A loop is conducted entirely wings level - from initial pull-up, through the vertical, the inverted and the pull-out, which means you start and finish on the same heading (or as close to it as most of us can manage). It is the most basic of aerobatic manoeuvres, which is why it is normally the first aerobatic taught to students.
A manoeuvre where you pull to the vertical, roll through 90 degrees and then complete a 3/4 loop to exit at 90 degrees from entry is called a quarter clover. It is very useful for positioning during displays.
It appears that the intended manoeuvre on this occasion was a quarter clover, or a modified version of same as the heading change was less than 90 degrees. However, only one person knows exactly what the intended manoeuvre was, and he is currently unable to tell us because he is still in an induced coma.
I hope this helps your understanding.
