Not really. According to the laws of cricket,when a team 
  is ahead on 1st innings basis, the captain can enforce 
  follow-on if: 

  1) 5-day match:   200 runs lead established 
  2) 3/4 day match: 150 runs lead established 
  3) 2-day match:   100 runs lead established 
  4) 1-day match:    75 runs lead established 

  Now if there is no play on the 1st day of a  test match, 
  the laws also specify that the match has become(in this case) 
  a 4-day match. Therefore the follow-on lead required becomes 
  150 runs. 

  Even Sir Garfield Sobers was once caught unaware and extremely 
  upset when India enforced follow-on in similiar circumstances against 
  his side at Kingston in 1971 He, of course, went on to make India pay 
  for this effrontery.
