Comments
By default, Windows combines ("coalesces") newly-freed adjacent blocks into a single block. Combining the blocks takes time, but reduces fragmentation that might force the heap to allocate additional memory when it cannot find contiguous memory.
This flag is used for maintaining compatibility with old applications.
