Exactly. The probe callback ensures that the file closed properly.
Refer to this
example
<http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/section-dynamic-pipelines.html#section-dynamic-changing>
where
a somewhat similar situation is explained.

For the three examples you gave:

avenc_mpeg2video ! filesink


Send the eos through the filesink sink pad. Don't bother installing the
probe. Just be sure that the event was sent by checking the return value of
the gst_pad_send_event.

avenc_mpeg2video ! mpegpsmux ! filesink


Install the probe on the filesink sink pad. Send the eos on mpegpsmux sink
pad. Once you enter the callback of the probe, your file should be properly
closed.

avenc_mpeg2video ! avimux ! filesink


Similar to the last example, just send the eos on the avimux sink pad.
