on edit: noting depends on if we consider as elements the words, or the letters.
The only way to compare the lengths of the two infinite sentences is by comparing their cardinalities. There is no other meaningful definition of sentence length for an infinite sentence. They have the same cardinality, so they're the same "length."
If its according to cardinality then no, they have the same cardinality, same number of elements, presumably letters. If its according to a measure, then sure, one can be longer than the other -- the subset of [0,1] of the real line has the same cardinality, same number of 'points' as [0, 100] but the latter is longer when you compare according to the Lebesgue measure, i.e. 'length'.
Since Buffalo -> is infinite and Police -> is infinite, but Buffalo is larger than Police how much larger is it?
It is obviously infinitely larger.

Buffalo buffalo buffalo buffalo -> infinite
and
Police Police Police Police -> infinite
certainly Buffalo and Police sentences can both be infinite but the Buffalo sentence is obviously larger than the Police sentence because Buffalo has 7 letters and Police only 6.
