Not really, you do the usual spell resistance test, witch is exactly the use of counterspelling that shielding applies to.

It may be the same dice pool, but you do something else. You are absorbing spells and you are not shielding yourself from spells. This is indeed an other use of counterspelling.

Would you add your Shielding metamagic extra dice for a Cleansing attempt ? It is after all based on a Magic + Counterspelling roll. Or the dices from a Counterspelling focus ? Reflecting is more accurate in it's wording : "To use Reflecting a character must be able to use Counterspelling during the normal Spell Resistance Test. As with Shielding, add initiate grade as a dice pool modifier.", and the base rules (SR4A p 198) says about Shielding "These additionnal dice are not gained for any other use of Counterspelling.", strongly hinting that you don't get to add your intiation rank twice.

Personnally as a player and as a GM I would not, so neither would I add them for an Absorption test - those are different use of the same skill. I view Shielding/Absorption/Reflexion as three alternatives rather than cumulatives way to counter a spell.

Obviously YMMW, but I strongly advise to check that with your table/GM to be sure that everyone is on the same page.
