I don't believe that autophagosome creation or fusion necessarily triggers lysosome biogenesis. Rather, lysosome creation is regulated by a number of factors (some of which are actively trans-nuclear) including total autophagosome load.
Let me know if that helps at all.
I liked this article

The LC3/ubiquitone tagging/grouping cascade results in an autophagosome (containing material to be recycled) waiting to be joined with one or more lysosomes. The result is called an autolysosome. As amino acids are liberated from this body, it might become a lysosome available for action again, along with more "de novo" lysosome biogenesis. I sense these bodies (lysosomes and peroxysomes) fuse and reform a lot like HDL/VDL/VLDL/chylomicrons.
