[gurps] A quick spell requirement question

[Clinton N. Fell]

I'm away from my books and wondering "If a spell requires 1 spell from 10 
different colleges, do spells that count as part of multiple colleges 
count multiple times?"

I.E.  Enchant requires the caster to know at least one spell from ten 
colleges.  And the caster knows Deflect Missile which is both a Protection 
college spell and a Movement college spell.  Does the Deflect Missile 
spell count as knowing 1 spell from 2 different colleges.

Thanks,

Clint
