No, I believe the "if (vfslist != NULL)" code was there to reduce the maximum column widths to those necessary for an explicit list of filesystems rather than using the maximum widths for all filesystems. The regetmntinfo() call before the "if" has already performed any operations that could hang indefinitely, so it makes sense to unconditionally use these up-to-date results instead of the potentially stale list from getmntinfo(..., MNT_NOWAIT).
