You didn't understand the point of the one minute offset. This was so
all directories in the CWD would hold the same time as an arbitrary
known unmodified point. To set the touch one minute in the past assures
that when we recheck to see if anything has changed, only directories
have been modified will have a variant of the timestamp by at least one
minute. See, we take the Doc's Delorean, hit 88MPH and go back in time
precisely one minute. When _anything_ in the filesystem is updated, we
have our variant(s).
It worked. I know, because I tested the case that you mentioned by
a script along the lines of
<my previous script stuff>
<my previous "did it change?" script stuff>
and I got the answers I was expecting.

I don't really understand why you are not allowed to extract into known
source directories? If it is due to the fact that some tarballs you
extract are overwriting dirs that are expected to be in CWD, could you
not contain all of the offending dirs into a single dir -- yes, you
have to reach out a bit deeper to get to the offending Makefile(s) but
you could then control the names of the extract directories. All in
it would make the scripts easier to write (I would think).
This is, in fact, what I'm doing in BuildRoot for proprietary code that
we are getting from our code repo. I make the offensive (usually third
party) code be one level deep and I supply a Makefile that preps the
build another level deep.
