Why do you mean so? Do DIKO voters prefer in 100 % DISY before AKEL?
Most people aren't voting for parties, but for persons. Papadopoulos is on the right wing of DIKO and has a very neo-liberal profile. His voters are very unlikely to go left.
In 2013 Malas and Giorgos Lillikas got 26.9 and 24.9% respectively, so the left/centre-left got a majority, which Malas then failed to consolidate behind him in the run-off.
This time Lillikas wasn't taken seriously and only got 2.18% (well below the 5.65% to far right ELAM) and the combined left/centre-left ended up with less than a third of the vote. Its a much more favorable situation for Anastasiades.
