1246	C.5.2.1 is confusing	fbossen		"C.5.2.1 ends with:

These processes are separately applied for each layer, starting from the lowest layer in the OLS, in increasing order of the nuh_layer_id values of the layers in the OLS.
NOTE – In the operation of output order DPB, same as in the operation of output timing DPB, decoded pictures with PictureOutputFlag equal to 1 in the same AU are also output consecutively in ascending order of the nuh_layer_id values of the decoded pictures.
Let picture n and the current picture be the coded picture or decoded picture of the AU n for a particular value of nuh_layer_id, wherein n is a non-negative integer number.

I am having trouble understanding what ""separately applied for each layer"" means. Also the last sentence defines ""picture n"" which appears to never be used.
