Unexpected growth of ASM data file after modification of next attribute

I had an ASM tablespace run out of free space.  I added a 250 MB datafile to the ASM disk group with no issue, except for the Next attribute being at 10 M, when I had meant to make it 100 M.  I executed 'alter database datafile <fileid> autoextend on next 100M' and the file went from 250MB to 4GB in allocated space.  I cannot figure out why this would happen.  The disk group is in Normal redundancy.  I had considered a template impacting the file size, but I didn't see any attributes that would set a minimum file size.

Does anyone know why this would happen?

Howdy, Stranger!
