Here is some logging that shows the behavior:

server2 executes the CreateIndexFunction and creates the index locally:
{noformat}
[warn 2020/03/12 16:18:11.273 PDT <Function Execution Processor2> tid=0x54] XXX CreateIndexFunction.execute indexName=cusip_index_1

[info 2020/03/12 16:18:11.297 PDT <Function Execution Processor2> tid=0x54] Created index locally, sending index creation message to all members, and will be waiting for response Index [ Name=cusip_index_1 Type =FUNCTIONAL IdxExp=cusip From=/Trades Proj=*]imports : null.
{noformat}
It sends the IndexCreationMsg to servers 1, 3 and 4 and processes the response:
{noformat}
[warn 2020/03/12 16:18:11.297 PDT <Function Execution Processor2> tid=0x54] XXX IndexCreationMsg.send indMsg=cusip_index_1 

[warn 2020/03/12 16:18:11.298 PDT <Function Execution Processor2> tid=0x54] XXX PartitionedRegion.createIndex response=<IndexCreationMsg$IndexCreationResponse 52 waiting for 3 replies from [192.168.1.4(server1:88452)<v1>:41001, 192.168.1.4(server3:88473)<v3>:41003, 192.168.1.4(server4:88480)<v4>:41004]>
{noformat}
servers 1, 3 and 4 receive the IndexCreationMsg, creates the index and respond:
{noformat}
[warn 2020/03/12 16:18:11.298 PDT <PartitionedRegion Message Processor2> tid=0x4b] XXX IndexCreationMsg.operateOnPartitionedRegion about to createIndexes

[warn 2020/03/12 16:18:11.304 PDT <PartitionedRegion Message Processor2> tid=0x4b] XXX IndexCreationMsg.operateOnPartitionedRegion done createIndexes
{noformat}
Then they execute the CreateIndexFunction to create the index locally which fails:
{noformat}
[warn 2020/03/12 16:18:11.501 PDT <Function Execution Processor2> tid=0x4e] XXX CreateIndexFunction.execute indexName=cusip_index_1
