It seems that org tries to convert times back and forth when evaluating
formulas; but, in your case, it cannot convert them because it doesn't
spot them inside your formula.

You could switch to the "Lisp" syntax (as opposed to the "Calc" syntax),
and, write the conversion manually:

    | 19:55:00 |
    | 40:01:00 |
    | 40:01:00 |
    #+TBLFM: $1='(org-table-time-string-to-seconds (if (<= @# 1) "19:55" "40:01"));T

Note that, for Calc, 'X:Y' means the fraction 'X/Y' of the two
integers X and Y:

   40:01 = 40/1 = 40
   40:02 = 40/2 = 20
   40:03 = 40/3
   40:04 = 40/4 = 10
