Yes.

If it does not update it then it does not know that you merged that
revision and it would have to check for it again in the future.
Otherwise it would not be able to tell the difference from when you
merged to the entire tree or just a part of the tree. For a single
revision merge like your example it is less of a concern as you are
unlikely to merge that single revision again. But imagine doing a
synch up merge. If it does not update the mergeinfo for the ranges it
processed then everytime you do a synch up merge it would have to go
reprocess all of those ranges to see if there were any changes for
those files in that range.

By processing the files it is also able to compact and collapse the
revision ranges to remove gaps. Again, if it did not do that then
when you merged a range later it would have to check each gap for each
file which potentially increases the network turnarounds.

Anyway, it is conversation better had on the Subversion lists as it is
not related to Subclipse.
