Subject Re: jackrabbit components (jcr2spi, spi2jcr, ecc.)

with reference to the SPI component figure on jackrabbit site,
i guess that, for example, a jsr170 call (implemented in jcr2spi box)
is mapped to a spi call (implemented in spi2jcr box), then this spi call is
re-mapped again in a jsr170 call in the same jackrabbit instance,
and finally this call is sent to the same jackrabbit instance core, or not?

i can't understand the mean of the two red lines.
