hls duration incorrect with split filter

Description
I'm trying to encode two video streams into an HLS file (fill & alpha). However, when I use the split filter (which I need for this) the segment durations in the manifest file becomes x2 (30s) vs the actual duration (15s).
ffmpeg -i M7HGQ8gA7Sf09Z.qt -c:v libx264 -g:v 100 -filter_complex:v "[0:v]fps=fps=25,split=2" -f hls -hls_time 4 -hls_flags single_file test.m3u8 -y && cat test.m3u8
