Yes, we had a thread on the www-smil@w3.org mailing list a few weeks ago
before "SOJA Cherbourg" was released. We went to the conclusion that
the time line should be:

-----------------------------------
Quoted from Sjoerd Mullender (sjoerd@oratrix.nl),

Sjoerd is the author of the SMIL Specifications concerning "repeat".
-----------------------------------
The intention is that the code

<seq repeat="3" begin="3s">
 <img src="foo1" dur="4s" region="reg1" />
 <img src="foo2" dur="4s" region="reg2" />
</seq>

is equivalent to

<seq begin="3s">
 <seq>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </seq>
 <seq>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </seq>
 <seq>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </seq>
</seq>

If we change this a little to make it even clearer, if in the example
you had par instead of seq, you would get

<seq begin="3s">
 <par>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </par>
 <par>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </par>
 <par>
  <img src="foo1" dur="4s" region="reg1" />
  <img src="foo2" dur="4s" region="reg2" />
 </par>
</seq>
