The direct reason is too big of the spaces among the grafts. If we are able to fill in all the spaces then the pluggy look will disappear. It is unnecessary to remove the big grafts. By not removing the large graft, they will help to increase the density and make the final result easier to achieve.
Please study the photos, to observe two facts.
1. Please notice the huge spaces among the grafts.
2. The large graft has the original density. Within the 4 mm graft, the distance among the hairs is kept in their original density. The hairs are appropriately spaced. The size of the graft is not the problem; the hairs are in their original form and not squeezed into a smaller space. The problem lies in the fact that the grafts (also known as plugs) are spaced too far apart from each other and the space in-between the grafts accentuate the pluggy look.

The goal is to fill in all the spaces between the punch grafts.
