Rsync is going to read the directory tree first, then walk it on
both sides comparing timestamps (for incrementals) and block
checksums.
Note that rsync only opens files and performs block checksums if the
source and destination modification times and sizes don't match.
You should not see most files opened during an incremental copy, unless
one of the filesystems is MS-FAT, where modification time has a 2 second
resolution, and it may not be possible to preserve a timestamp exactly
during a copy.
