Hi,
First let me mention, that the 
Mirror Operator (in this case operating on the X axis) would be recommendable in this case, instead of the 
Reverse Operator meant to reverse the order of elements in a 
Compose operator. To align these Segments correctly, you can override the 
Fixed Size having the 
Scale Segment option disabled of used "
Holders002" Segment or use negative 
Padding value. Please feel free to 
send us your scene to check it here. Thanks in advance.
Best regards,
