Release question

Hi Mathgroup,

I was trying to Plot:

   Plot[ {V[x], Phi[x] /. min}, {x,-5,5} ]

where min was a set of rules:

  min = {a->.5, b->.005}

Mathematica was literally trying to plot  "Phi /. min", which of course
is meaningless.

Thumbing through a book I have, I stumbled across the Release command.
This did work:

    Plot[ Release[{V[x], Phi[x] /. min}], {x,-5,5}]

I couldn't quite understand the explanation why Release is necessary.
Even though my problem is solved, can someone explain precisely why
Release is necessary here and what it does?

Thanks!
Peter
