Is it the intent of section 1021.2 to allow an R-
2 occupancy, three stories, fully sprinklered and
having emergency escape and rescue opening (EERO) sized windows - to also have a single exit to serve four dwelling units- only when there are no more than four dwelling units per story?

The answer is yes
Commentary
The limit is four dwelling units per floor; not four
dwelling units served by the exit. While it is true the
text alludes to areas served, it also requires compliance
with Table 1021.2 Table 1021.2 specifically says "dwelling
units per floor" in the column heading and "4 dwelling
units". The table does not say "dwelling units served by
the exit". In the example 8 units would exceed the limits
of Table 1021.2 and the area served would exceed the
allowances of the table. While not identical, this scenario
is consistent with the requirements of of the FFPC
s.30.2.4.4.
